HP Color Laser Jet 5

[Bob Smither]

(I know, I know, but I really like this boat anchor!)

The subject printer works great, except for the following:

I have it connected over a JetDirect (Ethernet) connection. Computers
are various flavors of Linux, fairly recent. This setup has worked for a
while.

Out of the blue, I now have the following behavior:

Printer when left idle enters Power Save mode.
First page printed after coming out of power save mode is fine.
Second and subsequent pages are offset horizontally
If left to return to power save, next page is fine.

The printed material is moved about a third of the page width to the
right. Note this printer moves the letter sized paper through
horizontally, so this appears to be some sort of paper registration or
handling problem.

Has anyone experienced this or have a trouble-shooting suggestion?

Thanks!

Look at the solenoids in the registration path - sounds like one may
be sticking. The rubber type material used for vibration dampening and
noise suppression becomes gummy and sticky over time and the solenoid
flap doesn't release rapidly. If left to sit (power save mode) it will
release but if multiple pages are printed it doesn't release in time
and you get the registration shift.
Hope this helps.

Jeff - that sounds pretty likely. As soon as I can get my son to help
lift the LJ5 for me I will check that out.

Many thanks,

Jeff - you are the man! Your diagnosis was spot one. There is a relay
on the left side (from the front) that raises and lowers a group of metal
tabs to stop and register the paper when it is first drawn into the
printer. That relay was sticky, preventing the tabs from stopping the
paper at the correct spot. Some dry lubricant and I am good for another
10 years!

Many thanks!
