HP printers have tiny rubber wheels (rollers) that help to feed paper into the printer and eject it from the printer. Over time, paper dust, debris, and other foreign materials get attached to these rollers, obstructing the movement of paper through the printer. So, it is always a good idea to clean these rollers periodically.
If you have recently encountered a paper jam or if there are stains and wrinkles on the printouts, you should clean the rollers of your HP printer. Some printer models even display a “Roller Cleaning is Recommended” message that indicates it’s time to clean them.
On HP Laser Printers
HP laser printers generally incorporate input, output, and ADF rollers. Depending upon the model of your printer, the location of these rollers may vary. You should first check the location of the roller and then start cleaning them.
Below is a step-by-step guide on how to clean each of these rollers. Here, we are taking reference of the LaserJet Pro 400 MFP M425dn printer for demonstration.
Clean the Input Rollers
Input rollers are those rollers that pick up the papers from the input tray and feed it to the printer. They generally lie on the rear side of the printer’s body.
Note: Strictly refrain yourself from using organic solvent and cleaners that contain alcohol. They make the rollers dry and can cause cracks in the long run.
- Power off your printer and remove its power cord.
- Pull the lock and open the rear panel access door.
- Dip the lint-free cloth into the distilled water container.
- Soak the cloth for a while and squeeze it to make it slightly damped. Do not use heavily damped cloth for cleaning.
- Use the cloth to clean the wheels.
- You can also get a blower and blow the dust out of the wheels.
- Also, check if there are any foreign materials like hair or debris attached to the wheels, and remove them.
- Use your finger and verify if the rollers move properly.
- Close the access door.
Clean the Output Rollers
Once the printer completes the printing, it ejects paper using the output rollers. You can access these rollers after removing the toner cartridge cover.
- Detach the input tray from the printer.
- Pull the toner cartridge door and remove the toner from your printer.
- You will see rollers after removing the toner.
- Soak a piece of lint-free cloth into distilled water and squeeze it. Make it slightly damped.
- Run that cloth across the wheels. Clean the wheels by moving the cloth up and down and to and fro.
- You may also use a blower to wipe out any dust and debris.
- Use your hands to see if they move freely without any blockage.
- Put back the toner and close the toner cartridge door.
- Re-insert the input tray into the printer.
Clean the ADF rollers
If your printer has an ADF (Automatic Document Feeder), it also has ADF rollers to supply papers to the printer. These rollers lie just below the ADF assembly of your printer.
- Remove the top cover of the ADF assembly. You will see two wheels attached to the top cover and a roller stick with two wheels on the paper path.
- You can use a toothpick to remove any debris or use a blower to blow the dust out of it.
- Then take the lint-free cloth, dip it in distilled water, and squeeze it.
- Use the cloth to clean the wheels and rollers.
- Verify if they move properly.
- Re-put the top cover of the ADF assembly.
Tip: If the roller could not move freely even after cleaning it up, you may get a silicone lubricating grease made for printers and apply it to the rollers.
On HP Inkjet Printers
Unlike Laser printers, most HP Inkjet printers only have an input and output roller. Follow the steps below to clean these rollers. Here, we are taking reference of HP Ink Tank Wireless 415 Series printer for demonstration.
Clean the Input Rollers
The input rollers on your HP Inkjet printer lie just behind the input tray. Follow these steps to clean them.
- Power off your printer and remove its power cord.
- Remove the input tray of your printer. If the tray is fastened using screws, first detach the tray by removing the screws.
- Keep the tray aside.
- Soak the lint-free cloth in distilled water and squeeze it to make it slightly damped.
- Use the same cloth to clean the rollers.
- If there are any foreign bodies attached, you may also use a toothpick or a blower to clean them.
- Keep cleaning the rollers till they move smoothly.
- Once you complete the cleaning, you can re-put the input tray and fasten them using the screws.
Clean the Output Rollers
The output rollers on HP Inkjet printers lie in the paper output path inside the output tray. You don’t need to disassemble the printer to clean these rollers.
- Push the output tray inside the printer.
- Look for the rollers in the paper output path. You may use a flashlight if you find it difficult to see them.
- Use a blower to blow any dust.
- Then take the lint-free cloth soaked in distilled water to clean the rollers. Strictly avoid using a wet cloth. Squeeze it properly before starting the cleaning process.

NASA propulsion technology brings flying cars closer to reality
Anyone who’s seen Blade Runner or The Jetsons knows that flying cars are essential to the “future,” but despite many people’s expectations, these flying cars Personal vehicles have always seemed a step ahead of what they are now. Now, one company says it holds the key to making these amazing flying machines a reality, and it’s based on a NASA-proven propulsion system that won’t be abandoned easily.
Applied eVTOL Concepts this week announced plans for a vertical take-off and landing (VTOL) vehicle, the Epiphany Transporter. The company says it has a top speed of 160 mph (258 km/h), but generates less than 55 km/h. h./h. decibels of noise at 50 feet (15 meters). This is somewhere between the volume of pouring rain (50 dB) and the volume of normal human speech (60 dB).
The secret seems to be the ducted motors on the sides and rear of the Epiphany Transporter. This motor, discovered in 2002 by researchers at NASA Ames Research Center, produces great thrust, the physical force that powers jet engines and helicopters.
This duct design also has the added benefit of protecting the rotating blades within the duct that generate the thrust. Rob Bulaga, his Epiphany Transporter project engineer at Applied eVTOL Concepts, is a co-author of the original paper. The design has been refined over the 20 years since it was first tested in Ames, and Michael Moshir, founder of Applied eVTOL Concepts, said the technology has improved since the concept was flying cars first tested in a NASA wind tunnel. I believe we have made significant progress.
We have complete confidence in the ability of our patented and field-proven air ducts and advanced aircraft designs to perform as expected in flight,” said Mosher, who is also the company’s CEO and principal designer. Stated. statement.
— NASA and the U.S. Air Force are introducing the new X-Plane X-66A to test Wildwing designs for economical flight.

— India successfully lands its first reusable spaceplane prototype (video)
The ship is designed to accommodate her two passengers and their luggage. The company says the Epiphany is roughly the size of a Tesla Model S and fits in a typical one-car garage.
Of course, just because a company’s ducted engine works fine in a wind tunnel doesn’t mean we’ll have flying cars anytime soon. Over the years, many vertical take-off and landing companies have come and gone, certainly including his NASA engineers.
However, it’s always sound engineering practice to use a proven design as a basis, so perhaps this will end up being the real deal.
Experts say building the giant bioreactors needed to mass-produce raw materials to make medicines, vaccines, cultured meat and more will require significant infrastructure and funding.
Matt Anderson-Baron, co-founder and CEO of Canadian company Future Fields, told TechCrunch that 10 billion liters of biodigesters will be needed by 2030, compared to the amount that exists today. said only 61 million liters.
Furthermore, recombinant proteins, which are the products of bioreactors, account for a large portion of the costs associated with cultured meat production, which may be part of the reason why the cultured meat sector has not been able to achieve price parity with traditional meat. It has become.
Future Fields believes it has discovered a more cost-effective and sustainable way to do this using EntoEngine. This is an approach that uses fruit flies rather than giant steel tanks to produce recombinant proteins.
“Traditionally, growth factors and recombinant proteins are produced in microbial systems grown in large stainless steel tanks, so they compete for the same infrastructure,” Anderson-Barron said. “We are replacing bioreactors with insects. We are genetically engineering insects that can be raised in simple plastic containers. This is highly scalable, cost-effective, and important. Best of all, it avoids infrastructure-related issues and frees up the supply chain for people who don’t have to create more demand, whether they actually need it or not.”
Anderson Barron, his wife Jarin Anderson Barron, and co-founder Reiji Ghafoor have been working on the issue for some time (the last time they covered Future Fields was in 2020. ), the company today announced that the facility will be used to launch its first products beyond cultivated meat (research, cell therapy, biopharmaceuticals) and to expand its team.
Bee Partners is joined by Toyota Ventures, Builders VC, AgFunder, Amplify Capital, BoxOne Ventures’ Milad Alukozai, Green Circle Foodtech, Siddhi Capital and Climate Capital in the round.
Anderson Barron declined to disclose growth rates, but said the team has doubled in size in the past year and has supplied more than 60 companies with animal protein products in the past 18 months.
Future Fields is building its first manufacturing facility near its headquarters in Edmonton, Canada, which will produce kilograms of recombinant protein in just 10,000 square feet of manufacturing space.
Meanwhile, the company’s EntoEngine technology will expand its portfolio of human recombinant protein products for medical research and biopharmaceuticals, including five of his proteins useful in wound healing, reproductive biology, muscle and breast milk development, and stem cell research. Offers.
Anderson-Baron said using flies offers both speed and scalability. EntoEngine’s Drosophila technology allows him to produce biomass 16-30 times faster than conventional bioreactors, producing protein every day in the same space and infrastructure.
“This is not possible with other systems that have bioreactors that run frequently for weeks and run one production cycle,” he added. “This gives us a lot more flexibility and, importantly, it allows us to scale much faster and at a lower cost, as it replaces stainless steel tanks that require insects to be plugged into the wall.”
(ADINet, Thai Meteorological Department, media)(ECHO Daily Flash of 17 Aug 2023)
Libraries are gradually moving from their previous role as ADINet “repositories” of knowledge to organizational centers for information exchange. Knowledge stored in the form of rare books, journals, other information materials and modern electronic resources is displayed in the library for users. The boundaries of libraries are expanding beyond their four walls and library professionals are preparing to take on the challenge of using libraries to disseminate authentic, relevant and correct information to their patrons.
Thanks to rapid progress in all fields, more and more documents are becoming available worldwide in both print and electronic formats. No library can afford to store all the documents needed for a user’s area of interest, but they can provide users with a “link” to find the information they need. Thus, networking and resource sharing have now become very important and such solutions are effectively provided by ADINET to users and librarians of all fields of knowledge and are widely used throughout the world.
In recent days, severe storms and strong winds have affected central and northern Thailand, especially the provinces of Phetchaburi, Chiang Mai, Surat Thani, Satun and Rayong, causing casualties and damage.
Media reported that as of August 16, one person was ADINet killed, one was missing and five people were rescued in a weather-related incident that occurred on August 12 in Bang Laem district in northeastern Phetchaburi province.
In addition, according to the ASEAN Disaster Information Network (ADINet), on August 16, 200 people and about 400 houses were affected by flooding in the provinces of Chiang Mai, Surat Thani, Satun and Rayong.
More heavy rain and thunderstorms are expected in ADINet most parts of the country over the next 24 hours, with some very heavy rain expected in northern Thailand.
Retinal diseases include many different types, including varying diseases and degrees of severity. It is not practical to train models with different types of diseases. When new patients with a disease appear, the model must be dynamically trained. Although deep learning methods have received a lot of attention in recent years, they suffer from fatal forgetting when performance drops significantly when a new training class is introduced. We found that maintaining the feature distribution of the old model helps maintain the performance of incremental learning. In this paper, we develop a framework called Attribute-Driven Incremental Network (ADINet), a novel architecture that integrates class label prediction and attribute prediction into an incremental learning framework to improve classification performance. Image-level classification uses knowledge distillation (KD) to preserve knowledge about base classes. Attribute prediction calculates weights for each image attribute and uses these weights to make more accurate attribute predictions. Design attribute distillation (AD) loss to preserve image information. When a new class is introduced, the attributes of the base class are learned. This additional training can be performed multiple times with some loss of performance. Experimental results on our proprietary fundus image dataset show that our proposed method outperforms existing state-of-the-art methods. To demonstrate the generalizability of our proposed method, it was tested on the ImageNet-150K-sub dataset and showed good performance.
