I have found some rubbing alcohol on a paper towel, set on top of the print heads will sometimes loosen the grunge. If I recall you can remove the print head assembly on an Epson, so you might try soaking it in a bowl of rubbing alcohol. Make sure you fully dry the print head before placing it back in use. Run your cleaning option a couple of times to recharge the head after cleaning.

SOURCE: The following printhead(s) has a problem Black/Yellow[K/Y].

Simple solution is:

Replace the Black and Yellow Print Catridges. The print heads are mounted to the bottom of the catridges and these, depending on whther they're from HP or not. can have a hard time conducting electricity properly, and in turn.. spitting ink out properly.


Also happens often with aftermarket Catridges because HP puts chips on the catridge. be sure to put an HP catridge. Sometimes you get what you pay for :)

SOURCE: HP D135 - replaced printhead - still doesn't print in that color

try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.

Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

SOURCE: Officejet d135 says bad black printhead- Replace the pentagon --

To solve the printing problem..


# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.

1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

# Reinstall the cartridges, making sure you snap them correctly into the printer.


Hope this help. Please Rate My Response! Thanks!

SOURCE: I have 2 Epson R230. One has a bad printhead, in

Befory you toss the printer, try this!
Take a syringe, 1" piece of rubber tubbing that will fit over the head input snugly, (auto parts house stocks some that works fine). Fill the syringe with a good head cleaner, slightly warm it in the microwave (try 5 seconds to start). Attach to nozzle, gently pull back just a bit, then apply a little pressure. If it accepts the fluid, STOP, You can clean the syringe, add the proper color ink, inject just a small amount. reinstall a known good cartridge, clean heads couple times checking results, if ANY streaks or color appears, clean again! Sometimes letting it sit overnight allows the head to fill with ink. I have had very good luck with this method, also some will not clean properly, just depends on how bad it is clogged.
Good luck..

Why is my dcp135c printing images in brown instead of black


Several probable causes of this.
  1. Your Black is empty and the printer is trying to approximate the Black using the other colours. Check and replace Black.
  2. Your Black printhead is blocked and all you are seeing is the other colours that are used to make the black into a full black. Check cartridge and do a printhead clean to see if this clears it. Also print off a print quality test sheet (In the Ink Management options on the printer)
  3. Another colour has been put into the Black Slot on your printer. Replace the incorrect cartridge and hope that the printhead has not been damaged by using the wrong cartridge. May need several printhead cleans to clear incorrect ink from the feed lines.
Hope this helps.

I recently changed my carriage belt.The print quality has ever been so bad.Does not print clear lines,especially with the black ink.Always have some white lines within...Thank you. Nima


The printhead for black ink cartridge could be blocked.

It is better to run the Clean Printhead operation on your printers tools option.

You can manually clean the print head so that next time when you execute the Clean Printhead from HP solution center it will be successful.

First, remove the printheads.
then, pull up the lever at the top of the cartridge holder, this releases the print head.

The print head could be blocked, most common is the dried ink blocking the small holes in the print head.

Washed it in running tap water. It is best if you soak it in a mixture of water and ammonia and leave it overnight.

After soaking, you can spray it with canned air and blow those little holes to unclog it. Once it dry, return the print head and the ink cartridges and performed the alignment.

Black ink does not print. Color works fine.


The print head is probably blocked then. You may be able to get a cleaning cartrige if you look online. Failing that, it will probably need a service.

Canon S600 bubblejet priner won't print color


In all likelihood, the nozzles in the printhead are blocked. The printhead is the carrier that holds the tanks. Remove the printhead and remove the tanks from the printhead. Flush the printhead THOROUGHLY with hot running water. You can also **** on the color discharge area (square and the black discharge area (rectangular) on the bottom to draw warm watr through the nozzles to further clean them. Dry the prinhead thoroughly, reinsert your tanks and reinsert the printhead in the printer. I then do a "nozzle check" to refill the passages in the printhead and get things flowing agan.
