HP Designjet 755cm Ink Cartridge FAQs

What do the numbers mean on HP ink cartridges?
The numbers on the ink cartridges are called cartridge model, part code or OEM code. These numbers help determine if the ink cartridge is compatible with your printer or not, as different printer models use different model numbers of ink cartridge. For instance, HP DesignJet 755cm printer uses a cartridge with a model number of HP 45 for black and HP 44 ink cartridges for color. This means that you can not use any other cartridge other than HP 45 and HP 44 ink cartridges as it is the only cartridge compatible with the said printer.
What do you do if your printer doesn't recognize the ink cartridge?
Make sure the cartridges are correctly seated on their slot. You can also unplug the power cord and other cables, then plug it back in, turn it on, and reload the cartridges after 15 minutes. While the cartridge is out of the printer, use a nonabrasive towel to gently clean the printhead to ensure that the cartridge chip and contact pin are free of debris.
