Firste I changede feedroller and sep pad and mylarsheet, but the problem continued so I changed the hole top (ADF) but the problem continues. 30.01.02. Do you have any idears?
30.1.2= A jam has occurred in the ADF. Recommend action, turn the MFP off and then back on to try to clear the message.
If the message indicates that a jam has occurred, clear the jam, if the message is still there. Check that the cable between the print engine and the scanner is secure..
Turn the MFP off, remove all memory DIMMS or third party DIMM from the MFP (Do not remove the firmware DIMM) remove all EIO device from the MFP. Turn the MFP on
if the erropr no longer exists, reinstall each DIMM and EIO device one at a time, make sure to turn the MFP off and no again as you install each device. replaced a DIMM
or EIO device if it cause the error, if problem persists upgrade the firmware before replaced the DC controller. Replaced the formatter and calibrate the MFP.
