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

The cyan print head nozzles maybe blocked.
Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

The exclamation mark means that the magenta printhead is already low in ink or have encounter a problem. Try removing and reinstalling the magenta printhead, if that didn't work, you will need to get a replacement for your magenta printhead since it could be low in ink.

Materials needed: New empty syringe (big one) Gloves (to protect your hands fromink) Alcohol Paper tissue (to clean the excessink) Empty Plastic bottle (Here you putthe ink from the syringe) Important: Ensure that you have put new Magentaink cartridge to HP K8600. Ensure that the printhead arerecognized by the printer or no light alarms. Instruction: Press the Power button to turn onthe printer. Test print in microsoft excel with4 color black/yellow and cyan/magenta. If magenta only is missing means youhave clogged problem from the host. Wear your globes, prepare thematerials needed. Open the top cover. Press and hold the Resume buttonuntil the carriage moves to the left. CAUTION: Be careful not to proceed until the carriage is on the left sideof the printer. If the carriage does not move to the left automatically, turnthe printer off and back on and then try holding down the Resume button again.The printhead can be damaged if the carriage is not all the way to the left forinstallation. Lift the printhead latch. Lift the handle of a printhead anduse it to pull the printhead magenta/cyan out of its slot. Put printhead in thepaper tissue upward. Your printer are still ON becarefull not to touch the flex copper circuit. Get your syringe, use this to pullthe ink from the nozzle cap ( see link picture) After the done the syringe method,Insert the printhead magenta/cyan into its color-coded slot. Press down firmly on the printheaduntil it snaps into place. Pull the printhead latch all theway forward, and then press down until the latch engages. Close the cover. The printer should align theprintheads automatically in a few minutes, printing an alignment page. Print a test with magenta coloronly, If it does not print, try to change the Printhead. This is the only solution I foundin my HP k8600 printing problem.

This document provides information on how to replace a printhead or ink cartridge.A printhead may need replacing when print quality issues cannot be resolved by cleaning the printheads or a front-panel display message indicates a printhead needs to be replaced.An ink cartridge needs replacing when a front-panel display message indicates either:

• Low ink levels
• Ink cartridge approaching expiration date

CAUTION: Never remove an ink cartridge and a printhead at the same time. Use the table below to identify the correct ink cartridge part number: Ink cartridge Part number HP 14 black print cartridge C5011A HP 14 tri-color print cartridge C5010A Use the table below to identify the correct printhead part number: Printhead Part number HP 14 black printhead C4920A HP 14 cyan printhead C4921A HP 14 magenta printhead C4922A HP 14 yellow printhead C4923A Replacing the ink cartridges Follow the instructions below to replace the ink cartridges:

Identifying parts of the printheads Use the table below to identify the parts:

1. Printhead handle
2. Printhead tower
3. Copper contacts
4. Plastic tape
5. Ink nozzles

Do not touch:

• Copper contacts
• Ink nozzles
• Printhead tower

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.

There are replacemetn parts for the print head, just like there is for the cartridge, though the expense may be more then the printer.

You can purchase a magenta printhead from HP's site here. Before you do that make sure it is the printhead - this model uses separate ink and printheads. Are you receiving an error message that the printhead is defective?

HP, in order to sell more ink, monitors the expiration date of the cartridges installed. Solution is either to buy a new unexpired cartridge from HP or to disable the date monitoring built in to the printer. This latter is done by removing the button cell located inside the D135 printer on the left hand side or by simply slipping a thin piece of plastic between button cell and metal contact. You will no longer have date function on printer, but it won't object to expired cartridges either.

Did you replace the PRINTHEAD, or did you replace the INK CARTRIDGE? They are not the same on the D145.

Good chance that you may have replaced the ink cartridge, not the magenta PRINTHEAD which sits under the ink cartridge.

PS - in my experience, non-HP ink cartridges clog up HP printers with separate printhead mechanisms... any possibility here?

Good luck!

Make sure the printheads are not expired. Check the dates. Order new from HP direct
