HP 934, 934XL, 935, 935XL Ink Cartridge Quick Tips

NOTE: Used“, “Counterfeit”, “Refilled or Depleted Cartridge Detected” and “Non-Genuine Cartridge”  alerts are COMPLETELY NORMAL for all HP 934, 934XL, 935 & 935XL black and color  ink cartridges which have been refilled and are initially installed into the printer. These nuisance messages may be bypassed and normal printing will be available. Since new replacement chips were installed, ink level monitoring will be available.  

 

TECH FLASH

For refilled HP 934/935 ink cartridge series printer models which display printer/cartridge error messages such as “cartridge missing or damaged”, “cartridge problem”, “cartridge depleted”, etc., and printing is not permitted, there is a new printer firmware update available for your printer model which will enable refilled ink cartridges to function normally (as of Sept. 2017).  Click on the link below; this will explain the issue & offer a printer firmware download to fix the issue and allow you to continue using refilled ink cartridges: click here

 

Usage Tips

1) Upon installation of a refilled HP 934, 934XL, 935 & 935XL ink cartridge you will observe various ‘Used’, ‘Counterfeit’ & ‘Non-HP’ alert messages. Choose ‘Yes’, ‘Continue’ and/or ‘OK’ to bypass the various nuisance alerts. This will enable normal print operations.

2) Since the HP 934, 934XL, 935 & 935XL cartridges have new replacement chips installed, ink level monitoring will be available.  NOTE: Upon refilled cartridge installation the printer may show a “Low Ink” alert message one time, simply select ‘OK’ to proceed.

 

3) During normal printing you will observe two levels of ink low warning messages – this is normal.

NOTE: A compatible/clone ink cartridge can be problematic; the embedded smart chip may not provide reliable printer-cartridge connectivity once installed. Compatible/clone cartridges are typically purchased on-line or at select retailers (i.e  sold under a different label than the regular HP cartridge packaging) and is essentially a “clone” of the original/genuine ink cartridge (if cartridge is original/genuine then the HP trademark logo will be displayed on the side and/or top labels of the ink cartridge). For the best refilling experience, only use HP original/genuine ink tanks. Most ink refillers will NOT refill non-genuine HP 934, 935, 934XL, 935XL ink cartridges.
