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.
NOTE: “Empty” and “Low Ink” alerts are COMPLETELY NORMAL for all HP 21 thru 58 ink cartridges which have been refilled! (select 15-58, 78 ink cartridges may allow ink level monitoring to be reset). 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’ up to six times to initiate the printing of the alignment page and/or scanning.
Continue to print normally until print quality fades.
For cartridge error messages which prevent printing (including blinking power/ink indicator/exclamation light), the ink cartridge may have an internal micro-electrical failure and may need to be replaced.
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.
