HP Designjet 800 error picture

SDimps · ‎08-30-2019

I have a problem which has occurred recently, but I have struggled to find an answer.

The error in the picture has appeared, there is also a flashing cross at the right hand side.

Is this repairable? or will it cost more than it's worth?

Looked through the service manual and couldn't see anything like the picture you posted.

What's the printer doing? Does it print? Does it respond to input from the control panel? Does it ever show any codes when booting up?

You might try removing all the ink cartridges and print heads. Then reboot and see what it tells you.

Parts are still plentiful and reasonably priced for this model. They're worth fixing IMO because they're probably one of the better printers HP put out. Check Ebay for parts availability. Or send me a PM. I have several parts that would work on this model.

I don't work for HP....I just repair their printers.

The right side houses the service station so. Over time these fill with waste ink and eventually seize up. Remove the right cover and observe the printer when fired up. Watch for movement in the service station.

Think I may have found the problem.

I recently had to replace the ink tube cover because of a broken clip.

I removed the cables from the Interconnect PCA shown in the picture, and I think I didn't reconnect correctly.

I removed them again and re-attached and once powered up, everything was fine, for now anyway.Interconnect PCA
