How to choose the right ink and printhead for the HP T1120ps

When selecting ink for HP Designjet T1120 Series, start with two simple questions: what do you print most often, and which colors run out first? XL cartridges are usually the best fit for busy offices, while standard capacities can be a smart option for occasional printing or specific spot colors.

Also, keep an eye on the printhead condition. Common user issues for the HP DesignJet T1120ps include:

• Missing lines or faint fragments in CAD drawings (often linked to nozzle issues or an aging printhead).
• Color shifts or uneven fills (frequently caused by a depleted cartridge, air in the system, or a printhead that needs replacement).
• Frequent cleaning cycles (can appear when ink is low, the printer is used irregularly, or the printhead is nearing end-of-life).

We encourage you to match the cartridge code (e.g., C9403A or C9371A) to the color you need and to replace printheads when the printer reports persistent quality problems. This approach keeps your plotter productive and helps avoid wasted media.
