Red will not print

I have dep cleaned many times but the red ink will not print. I have replaced the ink in case it was a problem with that particual ink cartridge but same problem. Should I buy a cleaning kit? This is a replacement machine for the one I had under warranty and only came with a 90 day warranty (Staples voided the 1st warranty when they replaced the machine- bogus)

    I also have color printing problems. I have cleaned, auto aligned the print heads, manually tried to align print heads, refreshed..everything and still the same issues. Sometimes it will come out of it on its own and just start printing colors again. But so far nothing. Maybe the print heads are gone?

Your User's Guide is available here:

http://files.support.epson.com/pdf/r1800_/r1800_ug.pdf

After leaving the printer inactive for a extended period you should expect the ink cartridges to be dried up and the print head 'gummed' in place.

You will need to refer to page 82 of the pdf, Cleaning the Printer.

As part of cleaning remove the existing ink cartridges and while the cartridges are removed try and clean the print head of any ink residue. Note that if the red light is on or flashing above an ink cartridge the printer sees it as empty (dried up).

The print head will not move if ink cartridges need replacement; replace ink cartridges according to the red lights, likely all. Press the ink button to see if the printer will begin the charging cycle. If all is well the green power light will stay on and the red ink light will go out.

If you do not get this desired outcome try Cleaning the Print Head, page 73 of the User Guide. Hold down the ink button when the red light is off for 3 seconds. Run a nozzle check pattern; if nozzels are not printing a clean pattern, repeat this process up to 3 or 4 times.

Print only red and black


First, use the HP Printing Assistant software to check the ink-level in the tri-colour ink-cartridge.
If empty, refill or replace the ink-cartridge.

Then, use the same software to run a few "print-head-cleaning" cycles,
just in case that some of the "colour" ink-jets are clogged.

Hi Good day!!!
Maybe your print head is clooged (red)
Then most about 98% are more likely to be an ink clog which just needs to be unclogged using something like print head cleaning solution
Basically, if a print head has been left unused for some time... moisture inside the ink begins to evaporate and instead of liquid ink, a thick inky jelly begins to form inside the print head.

When this occurs white lines appear in prints and most people not realizing the problem, will replace their inks... But when that does not work. Some assume they have an electrical fault, and replace their print head, others will replace their printer !

But provided there is no obvious print head damage? In 98% of cases it simply needs a little patience and print head cleaning solution injecting directly into the print head to dissolve the dried ink trapped inside. This will dissolve the clog and allow your expensive ink to flow once again. Most will then print as new.

Thank you for using fixya

Black printer ink in HP Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

I changed the black ink cartridge and the printer


Calibrate your new blank ink cartridge, have some nozzle check, cleaning check, and printer alignment. This are procedure that new ink cartridge will have to calibrate before you use. Epson printer are very sensitive when capable of changing ink cartridge. Unlink HP directly work without any print test because the cartridge head and ink join together, Epson with ink cartridge and the head separate.
Have some test on it at Printer Maintenance.
I'm sure 100% works on it.
Good luck!

Canon pixma ip4000 color not printing correctly with full inks


In both cases be sure using correct ink. Use of generic ink can lead to leakage of catrridge seats do to crossion from inferrior ink quality (per Cannon). Be sure ink in proper locations - see manual. Run the maintenance proceedures: cleaning then print nozzle pattern. If all colors are not proper after two or three cleanings, perform deep cleaning. Print nozzle pattern after each cleaning. This should clear up problem. If not, print head may need replacement.

Pixma MP830 is printing things green that should be red


when you change all new cartridges (make sure all cartridge ok, and the cartridge pins connection ok) still red color lost, it is the trouble at print head ink chanel some of that is too dry for longer time less using , most CANON printer head is separated from the ink cartridge, two way you may try:
1) take out the ink cartridge, drop down a little the special cleaner (best clean tools buy from dealer), to the head ink chanel hole, then set back the ink cartridge and waiting minutes
2) try put the print head bottom surface touch a little cleaner or water 1-2 hrs, if you can take out the print head unit. still not fixed for some case that should change the print head unit.

The actual print nozzle is typically on the ink cartridge itself, the casing of the print head is little more then a plastic holder for the cartridge. Before you replace the whole thing try this...
  1. Clean the plastic the color cartridge sits in with alcohol and a cotton swab. Especially where the copper makes contact.
  2. Clean the ink from the copper portion of the color cartridge and if possible replace the cartrige temporarily with a new one.

Hi,

Hope this will give you hints. To pin point directly you need to replace printer head. But before replacing please consider suction cartridge caps or nozzle by cleaning and freeing clogged airways by dettaching manually. I understand that the long time being not used has caused the problem. However if you can still use black and other colors then used it than complicating downtime in repairing procedures. Yes, you are right no need to clean deeper more than three times it will consume inks half empty. Have a nice day.

Besr regards,
