Question about HP OfficeJet Pro k550 Printer

1 Answer

Does not print red, print heads do not return to left parked area

This printer is networked. There are no error lights or warnings. The printer sometimes makes a chattering sound--like a plastic gear turning against a stuck gear.

It has now stopped printing red cleanly. We have tried the print head cleaning regimen--but this does not seem to work. We wanted to replace the print head--but the procedure for returning the print heads to the left side (turning the printer on--or pressing the resume key) do not return the printheads to the service area

The printhead not moving to the left I think I can solve. Open the top cover, the yellow light on the paper feed button wil come on solid, press and HOLD this button until you hear the print head assembly make some noises (about 10 to 20 seconds) then release the button and then the printheads will move and park on the left so you can remove the printhesd(s)

Head error after replkad


Remove the print heads and very gently clean the area on the printer and print head where the electrical contacts are. Do this with a Q-tip lightly moistened with distilled water. Be sure all surfaces are clean and dry before reinstalling the print head. If that doesn't work then your replacement print head is bad and you should return it to where you bought it or contact HP.

Canon ip90 4 blinks error


4 blinks is a purge unit error, that's the device that the printhead parks on on the right. Could be just a paper scrap inside, or the gears are worn out. The replacement includes the entire print engine and costs more than a new printer to replace.

Canon PIXMA iP4600 - error 6A80


Hello someone else here had this problem, this is what he posted: "Same problem with a Canon MP540 fresh from the box. Turned out to be the print head unit was not returning fully to the home position ie extreme right. My Fix : When the scanning unit cover is raised the print head unit moves left for access, look in the vacated area to the right, in particular the small black sponge where the head normally parks. I found a small spring jammed in beside the sponge, removed it and all is well. Don't know what the spring was meant to do but everything is working fine without it.On the MP540 the head unit now glows red, presumably meaning all is well... "

Epson stylus C88 makes black horizontal lines on the print


This "banding" is caused by uneven ink flow through the print nozzles.

Have you tried a cleaning cycle? If not, try one (right click the little printer icon in the bottom right corner of the screen and select head clean). Now run a nozzle check (right click the little printer icon in the bottom right corner of the screen and select nozzle check). Is there any sign of ink on the paper. Try up to three
cleaning cycles. If ink is now flowing, but not yet perfectly, don't carry out any more cleaning cycles. Just leave the printer for 24 hours (to allow any air in the print head to disperse). Then repeat the cleaning cycle/wait process. It may take a while to restore a perfect nozzle check print.

If you have already done lots of head cleans with no perfect results, are you sure you have good ink cartridges properly installed? The printer determines the amount of ink left in the cartridge by counting the number of ink "shots" when printing, head cleaning etc. This information is stored in the "chip" on the cartridge. Thus, it is not an actual measurement of the ink left, but an estimate calculated by subtracting the total shots from the original full ink quantity. This estimate can sometimes be grossly in error, usually due to a cartridge replacement not being carried out correctly. To eliminate this possibility, buy a new set of compatibles on E-Bay - they're very cheap. You can always re-use the old ones later if it turns out they DO have ink in them.

If none of the above works, then you may have blocked print head nozzles. You can try soaking the print heads for 24 hours (or more), as follows. Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid
comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If you get any black ink on the nozzle check, then there is hope! Repeat the process until you get a full black nozzle check. If nothing, repeat the process once more.

If still nothing, post a new comment detailing what you have done and the results.

Error light on stylus c62- printer makes loud buzzing


It sounds like the print head is jamming on the parking mechanism (usually because the actuation lever is stuck in the up position). Turn the printer on, and as soon as the print head moves, pull the power cord out of the back. You should now be able to move the print head over to the left by hand out of the way. Now look in the "parking bay" at the right end where the print head parks itself and see if there is a plastic arm sticking up. If there is, gently pull it towards you and it should spring down. Now turn the printer back on and it should operate normally. If it happens again, repeat the process a few times to see if it clears the problem. Otherwise it means the parking mechanism is gummed up with dried ink and needs a good clean (see below).

If you see that the whole parking mechanism itself has moved up to block the way, this means a spring has come off. To get this back on again requires the printer to be dismantled - as does the cleaning job above!

My epson C62 died while I was printing a document. The red light is on, green light off. the ink containers do not move entirely to the right where they belong. Does not respond to any signal.


This indicates a so-called "fatal" error. Because your print-head cannot fully move into its parking position on the right, it seems likely that the parking mechanism has come adrift. Turn the printer on, and as soonas the print head tries to move, pull the power cord out of the printer. You should now be able to move the print head (gently) out of the way and see into the parking area. If there is a plastic rod sticking up, ull it gently towards you and it should snap down out of the way. The printer should now work. If the problem re-occurs, it means the mechanism is clogged up with dried ink. Try repeating the above process a few times to see if it clears it.

If you see that the whole parking mechaism has come adrift, this almost certainly means the front spring has come off. This will require the printer to be dismantled I'm afraid, so will cleaning the print mechanism. Service Manuals are available to help with this.

Xerox 2424 Print head not parked


A copule of things cause that.
Here are the main 2.
On the left frams looking from the front, with the covers off, there is a 1 inch square stainless steel print head block that is located about 2/3s of the way back , near the bottom of the frame. Look at that and see if there is ink built up in that block , also under and around the block. If so remove the spring holder thats over the block and take channel lock pliers and remove that block. It may be very stiff. To clean soak it in hot water to soften the ink and clean that block, the shaft and all the remaining ink under the block you can remove. Once you return the machine to working order, take a level and out in on the glass. Make sure it is LEVEL front to back and side to side.
Number 2 is the print heasd wiper is stuck to the print head. That requires removing the scanner/document feed assembly, the side covers, the upper rear cover and the ink loader assembly,( where you put the ink sticks). Once you remove that you have access to the print hear drum area. If needed carefully pry the wiper from the print head and return to service. That blade will stick if the machine is not properly shut down.
I strongly suspect the machine is not level and when you ran the cleaning mode, it sucks all the ink out of the print head. Most likley while that ink was dropping into the tray, it ran out the back of the tray.
