Maintaining an HP Printer requires minimal maintenance and care. However, going through the simple steps of cleaning the printer on a regular basis can greatly improve the performance and lifespan of your printer. A good rule of thumb is to go through the process of cleaning off your printer any time you need to change an ink cartridge, change out the paper, or do other regular maintenance on it.
Unplug the printer and remove any paper.
Wipe off the outside of the printer with a soft cloth dampened with water and a very mild detergent. This should remove any dust, debris, and small bits of paper from the exterior of the printer.
Open the printer and gently wipe the inside area of the printer with a damp, lint free cloth. Wipe the rollers gently, and avoid getting excess water on any part of the printer. Make sure the cloth is barely damp and not dripping wet.
Remove the ink cartridges and wipe excess ink off of the bottom using a damp Q-tip, followed by a dry Q-tip. Replace the ink cartridges when you’re finished.
Close the printer and leave any damp parts to dry for about 20 minutes before plugging it back in and resuming regular use. After cleaning, you may want to run a print test to recalibrate the printer.
Never use alcohol or any alcohol-based product to clean a printer.
