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.
