Power goes off in the middle of printing. Power stays on consistently when I'm not trying to print

Hi

Try disconnecting printer from computer, power off and killing any print jobs in the print queue.

Then check that the printer powers on whilst un-connected to the PC, if light stays green, then the problem is related to PC interface. If the light goes red, then it's a hardware fault, maybe remove and replace cartridge, check no paper is jammed and try again.

Eventually all inkjet printers have this problem. When the printer is doing its thing (printing) there is a small amount of vaporised ink floating around the inside of the unit. This vapor collects on everything inside of the printing chamber, including the sensor strip the printer uses for tracking the print heads location. Luckily it's an easy fix, just clean the sensor strip.
To do this, get yourself some rubber gloves (unless you don't mind having Technicolor hands that is) and some lint free paper towels. Put the gloves on, then wet half a sheet of paper towel so its wet, but NOT dripping wet. open the printer and allow the ink heads to travel to middle. When they reach the middle, unplug the machine so the head stays unlocked and out of home position (where the print head goes when not printing). With the printer unplugged and the print head unlocked, locate the thin semi transparent strip running from one side of the printer to the other, it sorta floats there in mid air as its supported on either side by small metal tabs. Starting at the print head home position , gently, clean this strip with the wet paper towel, making sure not to apply too much pressure as you can pull the strip off the hanger tabs or erase the small lines printed onto on the strip. Once the home position section of the strip is cleaned, dry it off and slide the print head into it's home position and clean and dry the rest of the strip. When done, plug in and power up the unit, then do a test print to ensure the problem is fixed.
Hope this helps.

Stuff like this happens sometimes when you have a bad connection or if the print job is interrupted in the middle by the user cancelling it or a problem on the pc. I would check the cable to make sure that it is securely plugged in and retry it. You didn't say if this problem was recurring or not. If not, just try printing again. Let us know if this happens consistently. Good luck!

I went to the HP website and asked the question - got to a download of a diagnostic utility. Ultimately, solution was probably the restart of the computer - I hadn't tried that yet because of being in the middle of something.

Hello sir; you need to clean print head and cartridge seat, follow the steps; turn power on open top cover (as when you replace cartridge)let the cartridge carrier move to the center the UNPLUG the power the carrier will stay in the middle you can it freely, move it away from seat should find alot ink stick, remove it, clean out wipper blade and print head it should take care of your problem.

A couple of things I would try:

• Start the Print Server, then insert the USB cable.
• Plug in a self-powered USB port, and plug the printer cable into that. That could help if the print server is having trouble with the amount of power drawn by the printer.

Dear sir; this is a very comon problem,most people don't know how to take care of, now power on, open the cover until cartridge move and stopin the middle, then UN-PLUG (not turn off) the power cord,let the cartridge stay in the middle,now push cartridge all the way to the end opposite of cartridge seat,use Q-tip with water to clean print head cleaning blade,may be also you can see a ink sticker, remove it, make sure cartridge print head is ok,let me know the resolve. GOOD LUCK !!!

Did you check to see if the ink was low in the printer? Epson wont let you print if the ink is low, happened to me before!
