HP Laserjet P4014, P4015 Perform Printer Maintenance Message

The Perform Printer Maintenance Message on a HP laserjet P4014 and P4015 is a result of hitting the 225,000 page count mark. After the machine reaches 225,000 copies this message comes up on the control panel and you should install the printer maintenance parts and reset the perform printer maintenance message per the kit instructions. Most people at this time call in for service because they are unsure of what to do. While I recommend calling a technician to have them do it so they can clean and check over the machine to verify its ready to handle the next 225,000 copies. You can always do it yourself or if you have someone with minimal technical skills they should have no problem handling the job. The kits are designed to be user replaceable. Most come with instructions on how to reset the counter, part installation, and most, like the P4014, P4015 printer maintenance kit, don’t require any tools.

Xerox XD 100, 102, 105, 120, 130,155 H4 Error and Drum counter Reset

In this article I’d like to discuss the Xerox XD 100, 102, 105, 120, 130,155 H4 Error and Drum counter Reset.

DIAGNOSTICS:
To enter diagnostics: Turn on the power and within 4 seconds press the following sequence: ‘Clear’, ‘Exposure Mode’, ‘Clear’, ‘Exposure Mode’ (Exposure Mode is the button on the far left). The console will go completely blank.
To enter a code: Select the first part of the code using the copy quantity buttons, followed by the ‘Print’ button, then the second part of the code followed by the ‘Print’ button again.
To exit diagnostics: Press ‘Clear’ repeatedly or turn the power off.
*To clear a fuser code:(14) Enter diagnostics, select ’14′ followed by ‘Print’… exit diagnostics.
**To Clear a U2 code:(16) Enter diagnostics, select ’16′ followed by ‘Print’ … exit diagnostics.

Checking the Total Copy Count:(22-5)
Enter diagnostics, select ’22′, ‘Print’ followed by ’5′, ‘Print’…The copy count will flash 3 digits at a time for a total of six digits (for example: 012 345 would indicate 12,345 copies).
(Can also be done by the customer by holding the ‘Clear’ button for 7 seconds)

Checking the Drum Cartridge Count:(22-12)
Enter diagnostics, select ’22′, ‘Print’, followed by ’12′, ‘Print’…The copy count will flash 3 digits at a time for a total of six digits (for example: 002 345 would indicate 2,345 copies).

Drum Count Reset:(24-7)
Enter diagnostics, select ’24′, ‘Print’, followed by ’7′,’Print’, followed by ‘Print’ again. This resets the drum count to zero.

Xerox Workcentre 3210, 3220 System Error Cycle Power or Fuser Error

Once in a while one of the thermostats in the fusing unit gets stuck in the open position resulting in a system error cycle power or fuser error on a Xerox Workcentre 3210, 3220 . When the fuser reaches an overheat level the thermostat opens like a fuse and opens the AC voltage going to the fuser resulting in a fuser error or after start-up a System Error Cycle Power Message on the display. The thermostat is supposed to reset itself once it cools off but in some cases it sticks open and has to manually be reset. In this article I’ll explain why the Xerox Workcentre 3210, 3220 System Error Cycle Power or Fuser Error happens and how to fix it.
Xerox Workcentre 3210 / 3220 Fuser Unit, 126N00330, JC96-05133A 

1. Remove the Duplex Unit.
2. Remove the Rear Cover.
3. Remove the Rear Guide Unit.
4. Disconnect the wiring harness connector CN53
5. Remove 4 screws (12 mm, silver) that secure the Fuser.
6. Pull the Fuser out from the printer.
7. Remove 2 screws (10 mm, black) that secure the Thermostat on top of the fuser.
8. Lift the Thermostat away from the fuser cover.
9. Disconnect the wiring harness connectors CN49 & CN50 from the Thermostat.
10. Remove the Thermostat.

If one is stuck when you press down on the two thermostats you will notice that one depresses and springs back making a clicking sound while the other stays down. If you have a volt meter with a continuity test option if both thermostats are closed you should be able to put the leads on either side and have continuity. If not, then you know for sure one of them is not working correctly. Take a can of canned air and hold it upside down while spraying the thermostats and you should hear one pop back into place or if you depress them again they should act the same way. All were doing here is giving it an extra shot of very cold air so it resets the way it should have. Reinstall the thermostat,  fuser,  the covers and you should be good to go. More and more machines are using these thermostats becuase in theory they reset themselves rather than having to replace. I’ve seen them on Dells, Brothers, and Samsungs. If you have any questions feel free to send me an email and I’ll help you walk through the procedure.
