customer is getting these images on their print every now and then. a colleague says it could be the laser diode unit.

could be the LD, more likely the HD.

Looks like a data transmission problem. Does this happen when you run diagnostic test samples ? If it does not, suspect the communications part of the printer, NIC card/network card.

Did you have your probleme in copy mode or printing mode?
Do you have your probleme when you print SMC data?

I have had similar probleme and it was memory card of printer option .
And one time ,the default was IPU boad but probleme was only one copy mode

It looks like electrical noise causing laser to write, try plugging in on a different circuit.

Hi.
Try removing and looking in laser to see if all ok. Check laser mirror motors. It may be worth dropping the NVRAM and doing a all clear as well as formatting HDD. ( don't for get to print the Nn standard data. ) Far cheaper to try this first. Good Luck

customer says it did this like every 20 prints from computers. when i printed the smc there was no line.

[spaceman99]

Did you formatt HDD ? One thing to try.
If you have a Laptop it may be worth connecting via a Crossover and try printing doc;s from you Laptop by passing thier network and drivers.

IPU is use on copy and printing mode.
When you print SMC data you don't use IPU

Electrical noise/arcing from a bad charge connection is possible. Seen odd stuff like that with bad dirty coronas on the bigger boxes.

My vote is for fitting new HDDs - 2x standard 3.5" 80G or larger drives set to master. Run the SP code to copy the stamp data over. Backup the address book first if they use scan to email or scan to folder (address book maintenence - backup in Web Image Monitor)
