HP Laserjet 4101 errors 30.01.18 and 30.00.01

Intermittent problem-Cust reporting the 30.01.18 error, event log shows both errors.  I have checked cables, updated the firmware, replaced the jet direct card, scanner controller board, and the formatter board.  Cust says they are uncertain exactly when the unit errors our or what causes it to fail.  They don't seem to have any problems when they print to the unit.  It will be displaying the 30.01.18 when they walk up to the unit to do a copy, fax, etc. but the display will show the error before they start the copy or fax procedure.  Cust will power off/on & unit is good for a while.  All suggestions welcome.  thanks, jerry

    You may already have this but check page 124 in the Service Manual for details of the likely causes. It sounds like you've got an intermittent fault on the scanner controller board that the power cycling is resetting.  As you've already replaced the board try reseating it.

    Late in getting back to you-my apologies.  I had a reply from an HP forum from a tech that had the exact same intermittent issue.  He replaced the scanner power supply & it took care of the issue.  I replaced the scanner power supply & while removing the old one, I noticed a large capacitor that had a very slight, but definite bulge on the top.  This was just a few days ago, but what was a 10 times a day issue, has not shown up since.  Crossing my fingers, toes & what else will cross.  Thanks for taking the time for your reply.  jerry
