Known issues This section describes known issues and solutions for the HP LaserJet M5025 MFP and HP LaserJet M5035 Series MFP devices. The following issues are described in this section: ● Control-panel ESD disruption ● Clearing a jam from the right (print cartridge) side ● Loading Tray 2/3/4/5 with letter or A4 media ● The stapler/stacker only staples letter and A4 media ● Formatter cage does not properly seat ● RFU with a SCB firmware upgrade ● RFU with a DC controller firmware update ● EIO device does not properly seat ● Print cartridge cannot be removed ● False left door open error message ● Dark or flickering control-panel display ● Fuser edge overheat slowdown Control-panel ESD disruption Electrostatic discharge (ESD) can cause the control-panel touch screen alignment to be lost. If the control panel does not respond when touched, or if it responds erratically, you might need to align the touch screen: 1. Turn the power off. 2. Hold down the C and # buttons and turn the power on. 3. Release the C and # buttons when a small square appears in the upper-left portion of the controlpanel display. 4. Touch the small square in the upper-left portion of the control-panel display. A second small square will appear in the lower-right portion of the control-panel display. NOTE The first square does not disappear when it is touched. Take care to not touch it a second time or the calibration procedure will fail. 5. Touch the small square in the lower-right portion of the control-panel display. When you do, the touch screen alignment is complete and the device returns to power-on initialization. 6. If the dispaly is erratic, make sure that the most recent firmware upgrade is installed. Clearing a jam from the right (print cartridge) side For jams that are cleared from the right (print cartridge) side, open the left door to release the fuser nip pressure to make it easier to remove the jam.
