Safety First: Before You Begin HP Maintenance
Warning: You must disconnect the printer from the mains and allow it to cool, especially the fuser, before beginning any HP printer maintenance. If you fail to do this, you risk serious danger of getting burned.
| Maintenance Safety Warning | Best Practice |
| Heat Hazard | Disconnect the printer from the power source and let it cool completely before touching internal components. |
| Cleaning Agents | Avoid using ammonia cleaners; they can damage the printer. Use only a dry cloth or one moistened with water. |
| Vacuum Cleaners | Do not use a regular vacuum cleaner to remove dirt or toner; you can damage the printer. Use a micro-particle vacuum or a dry cloth. |
| Toner Exposure | If toner gets on your clothes, only wash with cold water, as warm/hot water fixes the toner, leaving a permanent stain. |
1. HP PRINTER CLEANING (Before Installing New Supplies)
It is highly recommended that you clean the entire printer set before installing a new toner, fuser, or maintenance kit. By cleaning thoroughly, the new supplies will not be affected by old dirt, allowing them to run on optimal conditions.
Cleaning Steps:
- Remove the Toner: Remove the toner cartridge to clean better. Crucially, cover the cartridge and prevent it from receiving direct light.
- Make sure the Interior is Clean: Clean the printer with a damp cloth; the cloth should not loose threads.
- Avoid the Roller: Try not to touch the transfer roller (the black roller located under the toner), as touching it can cause a loss in print quality.
- Clear Paper Path: Leave perfectly clean all the way to the blade still in the printer. To do this, introduce a transparency or cardboard for each slot to release the dirt, which avoids future paper jams.
- Clean Rollers: Clean all rollers that move the paper through the printer. You can get the dirt out using a cloth dampened with isopropyl alcohol. (Exercise care, as isopropyl alcohol is flammable).
2. CHANGE FUSER HP
The laser printer fuser has a limited useful life. Replacement becomes necessary when it starts making noises, loses print quality, or shows error codes.
- Error Warning: The printer typically warns you of the need for a change by generating fuser error code 50: 50 HP Fuser Error.
- Action: When these signs appear, its replacement will be necessary with a new or remanufactured fuser.
3. HP MAINTENANCE KIT CHANGE
You should check the user manual for information on when to change the maintenance kit.
- Timing: Maintenance kits need changing every few thousand prints (the exact number varies by model).
- Signs of Failure: If the printer keeps jamming and the print quality is lost, it will be necessary to put a new kit in the printer.
- Kit Composition: The maintenance kit consists of a fuser and a series of rollers that guide the paper through the printer; its composition varies and is specified for each HP laser printer model that needs Printer Repairs.
Follow these guidelines periodically to maintain your HP laser printer in perfect working condition.
