Cannot clean heads

The maintenance code 4000 for the Epson Stylus Pro 7890 indicates that the print head are starting to clog. You should power cycle the printer (turn off and then back on) to clear the error code. Then enter the maintenance menu and do a power cleaning. Make sure that paper is loaded. Then press Menu on the printer's control panel and press the down arrow until you reach the line "Maintenance". Press the right arrow to enter the sub-menu. Press the down arrow until you reach "Cleaning" and again press the right arrow. Press the down arrow to highlight "Power Cleaning" and press OK to start the cleaning routine. (You can do a nozzle check before and after to check how well the printer heads are working after the cleaning cycle.)

The information on Power Cleaning is on page 5 of the Quick Reference Guide, https://files.support.epson.com/pdf/pro789/pro789qr.pdf , and page 151 of the User's Guide , https://epson.com/Support/Printers/Professional-Imaging-Printers/Epson-Stylus-Pro-Series/Epson-Stylus-Pro-7890/s/SPT_SP7890K3#manuals . The Nozzle check is on the previous page.

I hope this helps. The Epson FAQ about the error code is here: https://epson.com/faq/SPT_SP7890K3~faq-298430?faq_cat=faq-8796127406156 .

It sounds like you have already tried a few steps to address the issue. Here are a few more things you can try:

1. Turn off the printer, unplug it from the power source, wait a few minutes, and then plug it back in and turn it on.
2. Check to make sure the printer is not in an error state. If it is, clear the error and try printing again.
3. Try cleaning the print head manually. To do this, remove the print head and use a soft, lint-free cloth to clean it. You can also use a cleaning solution designed specifically for print heads.
4. Check the ink cartridges to make sure they are installed correctly and have enough ink. If they are low or empty, replace them.

If none of these steps work, it may be best to contact Canon support for further assistance. They may be able to provide additional troubleshooting steps or offer a repair service for your printer.

Epson printer print head is cleaned manually or cleaning cycle. Use the cleaning cycle to clean the print head clogged nozzles:

It could be that the cartridges are not inserted properly in the carrier or just needs cleaning. Try to remove both cartridges from the printer and manually clean the nozzles. You may refer to this article on How to Clean the Print Cartridge Nozzles and Contacts Manually. Then reinsert one cartridge first and close the cover. If no error appears, reinsert the other cartridge. Replace whichever cartridge is causing the error. You can also try the Clean Cartridge function on the printer by pressing the Setup button -> Maintenance -> Clean Cartridges. It will then print the clean nozzles test page. If error continues, replace the faulty cartridge.

Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41,49 or 4F the print head is defective.If the
error is 50 or 51 there is error in Purge unit and printer require service.If the error is 48 - defective print head cable or circuit board.If the error is 46 the waste ink tank is full.Follow this:
1. Pres 'menu', 'mono start' then 'menu' one by one...
2. Press the arrow up or down to go to 'maintenance 80'.
3. Press 'mono start' several times to go to 'Purge'. Finding the PURGE will show some numeric value
which is Iassume the number of times the printer had cleaned.
4. Press 'arrow up' key and scroll for number "2" then press "set".Do the same for numbers 7, 8 and 3.
After you have entered this combination, the purge numeric value will be reset to 00000.
5.Restart printer

You manually rotated the aluminum drum? Since you did that, I would suspect you have the print head wiper blade stuck between the drum and print head. The code you are getting it caused by the print head not being able to move freely.
The jamming is probably due to a bad registration clutch. Common failure on that machine.
You can go to Xerox.com, there is under documentation and drivers a parts list for that machine. You can reference the wiper blade and get the clutch part number there.
Let me know what other information you may need. I will be glad to help you get it running again.

6975 I know of nothing that references.
I honestly don't know where you could get a manual. Other then try googling "the parts drop" and calling them. Talk to Britt.
Normally that print block is sticky or the cleaning blade is stuck to the print head causing that error.
