Question about HP LaserJet color laser printer
I have a color laserjet 4700. It is not completing the boot process.
It runs through the memory check, then just stops.
I have tried removing the EIO card and all of the added memory.
The fan comes on shortly after powering on.
The memory check is the only thing displayed, it gets stuck displaying:
Can anyone help?
Check if fuser and toner cartridge and image transfer belt are properly installed. Also check if covers are properly closed. One more thing, disconnect printer from main power for a couple of minutes and then turn it back on. Hope this helps. Maybe you can tell me what happened before this started(ex. paper jam).
