I experienced a paper jam which I corrected. After cleaning up the mess I decided to clean the print heads. I do not use the printer's cleaning cycle because it uses too much precious ink. I remove the ink cartridges and clean the heads with a solution that is supposed to be made specifically for Epson printers. I have done this dozens of times with excellent results. However, this time after I reinstalled the ink cartridges and fired up the printer, it went through all the motions of printing, but produced nothing but blank pages. There was no indication of a problem. The printer indicated that I had sufficient ink and that all was well. I uninstalled the printer software and then reinstalled it. Same result. Blank pages.

Any help with this mystery will be most gratefully appreciated.

After ’s manual head soak (and the basic checks suggested by and ), a short, targeted diagnostic path helps separate a driver/queue problem from a physical ejection problem. Print a nozzle‑check pattern from the NX‑400 control panel (Setup > Maintenance > Nozzle Check). The pattern shows which color channels are actually ejecting and is the single best first clue. (files.support.epson.com)

If the nozzle check is totally blank or very faint for all channels, a common result after manual soaking is that cleaning fluid or trapped air is sitting in the nozzle plate and dampers rather than fresh ink. A controlled, targeted flush/prime using a compatible piezo‑flush fluid and a syringe/dummy cartridge is the usual next step: push/pull small amounts of flush through each channel until ink returns, then run a couple of head‑clean cycles and recheck. InkjetMall documents the syringe/flush procedure and offers a small‑format flush kit (the NX‑400 is listed among supported models). Take care: use only recommended flush fluids, apply only gentle pressure, avoid household solvents, and follow the printer’s warnings (do not power the NX‑400 off during cleaning/charge operations). Improper flushing can permanently damage the head. (shop.inkjetmall.com)

Also inspect the cartridge chip and the gold contacts in the carriage for ink or debris and wipe them with a lint‑free cloth as Epson recommends; check under the head for any leftover paper towel fibers or pooled cleaning fluid that could block printing. If a targeted flush plus contact cleaning do not restore a nozzle check, the printhead or its carriage electronics has likely failed and service or head replacement is needed—contact Epson or an authorized repair center and supply the model/serial plus the nozzle‑check results. (epson.eu)

Summary: use the nozzle check to document which channels are dead, attempt a careful flush with a compatible kit if comfortable, clean chip/holder contacts, and escalate to service if the nozzle check still shows no ejection.

Are the cartridges fully seated down?
Have you tried with new cartridges (that would confirm if it was a cartridge problem) as sometimes the very very small jets can get blocked and if a solution dries on them it can be very difficult to remove the blockage!
Finally some epson printers have an electronic chip in the print head that detects if everything is ok but those chips do not always send messages when the error is one it does not know. it could be that if yours has a chip like this it is the chip that is awol and that also can be checked with new cartridge!

It seems to me to bhe unlikely that ther eis an electric fault such as cables but have you done a test print page (either from the computer or better many printers have a start up routine that you can hold down a button to force it to print a test page. if that gives blanks seems cartridge problem.

Have you checked the inkjet cartridges for your printers. It is better to also check the placement of your Epson inkjet cartridges as well. Confirm the presence of ink in the cartridge and if no ink is present than you can buy new Epson Inkjet Cartridges or Remanufactured Epson Inkjet Cartridges at cheaper rates and same good quality as original.

Remove the ink cartridges and clean the heads with the solution that is upposed to be made specifically for Epson.
Do not go for cleaning cycle.
After this process,i am sure your problem will be solved.
