HP 336, 337, 338, 339, 342, 343, 344 & 348 Cartridge Quick Tips

Cartridge Installation

Remove temporary protective storage clip and insert cartridge into your printer.

Retain the storage clip; use it on cartridge after it becomes empty as you return it for refill.

Usage Tips

NOTE: “Empty” and “Low Ink” alerts are COMPLETELY NORMAL for all HP 336, 337, 338, 339, 342, 343, 344 & 348 ink cartridges which have been refilled!  While at first this may be an unusual workflow, it does allow print operations to proceed.

Your printer/computer may display an ink alert message, such as “non-genuine cartridge”. Press proceed/continue/accept/yes/OK to dismiss this prompt.

After refills, the printer cannot track the ink level.  The ink level indicator will falsely signal empty. In many cases, additional nuisance messages may also appear – this is normal. Bypass all low ink warnings and nuisance alert messages.

If the printer/software prompts you to align the cartridge, perform the alignment at the printer’s control panel. You may need to press ‘OK’ (or resume/copy) up to six times to initiate the scanner.

Continue to print until the print quality fades.

Keep a spare set of cartridges, for convenience.  As an in-printer cartridge is depleted, remove it for refill.  Insert the spare into the printer and save the refill as the next spare.
