How to fix the 59.F0 Error
The 59.F0 is a common error code on the CP and CM, and M version HP Color LaserJet products. Printers such as the HP Color LaserJet CP3525, CP4520, CP4525 and the Multifunction CM4540 encounter this issue often.
Even the newer M477 and M452 encounter this issue. This typically means that the Fuser Drive Gear Assembly could be defective. This could also be the fault of the printer transfer belt or even the belt presence sensor. Either way, diagnosing the issue could be time consuming and costly.
We recommend starting with the transfer belt itself. Remove the belt from the printer. On the right-hand side there is a white round protrusion that engages the belt with the drive assembly. You can rotate this clockwise (2) to rotate the belt and if all goes well, unlock the sensor flag into position (1).
If the flag fails to engage downwards, then replace the belt. This is a common issue on the CP3520, CP4520 and CM4540 series products.
If replacement of the belt does not resolve the issue, then it could either be the Fuser Drive Gear assembly or the solenoid located on the assembly. Gaining access to this assembly is time consuming and could take up to four hours. Due to the amount of assemblies required just to gain access to the Drive Assembly, plan on at least two hours
to obtain access to the solenoid itself.
Much like the solenoids that release to engage Tray 2 drive, these may also be sticking due to the wear of the noise dampening sponge, which can expose the glue causing the timing of the Fuser Drive Gear to slip.
The picture above shows the Fuser Drive Assembly removed from the machine. The highlighted screws are required to be removed in order to access the solenoid.
The next picture shows the access point of the screws on the assembly still located inside the printer. These screws are accessible by removing the back cover, DC Controller, Low Voltage Power Supply and High Voltage Power Supply (both upper and lower).
The Main Drive Assembly (MDA) is not required to be removed to gain access to
the solenoid. After removal of the solenoid, denatured or 99% alcohol can be used to remove the glue.
Electrical tape can be applied in order to act as a noise dampener. It is also recommended as to eliminate the magnetic charge that could build up when the solenoid arm strikes the base.
The solenoid is not always the issue. If the sponge is intact, and it does not stick, the Fuser Drive Assembly may very well be the issue. The solenoid is not an available part, nor does it have a part number.
The Fuser Drive Assembly part numbers are as follows:
HP Color LaserJet CP4520 CP4525 Simplex RM1-6702-000
The level of this repair is a 9 out of 10. Depending on the level of technical expertise, this procedure should take approximately four to five hours from start to finish if replacing the Fuser Drive Unit Assembly. For technical assistance or to schedule a training module
