HP DesignJet T920 Ink Cartridges
Your HP DesignJet T920 printer uses the HP 727 and 727B ink cartridge series. Ink Depot has been supplying reliable consumables for this 36-inch large-format CAD printer since Jun 2015. High-volume technical printing typically consumes matte black ink far faster than accent grey or colour channels, making the 300ml 727B (3WX19A) cartridge a practical choice to avoid print job interruptions during architectural plan outputs. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected page output and ink usage
Page yields for HP 727 and 727B ink cartridges are calculated in accordance with ISO/IEC standards based on 5% page coverage. Technical CAD plotting and line drawings consume ink at different rates compared to full-colour graphics, with high-capacity matte black cartridges delivering significantly lower per-page ink consumption during continuous plan printing.
Optimising your cartridge setup
If you print mainly line drawings and architectural plans, purchasing 727B (3WX19A) matte black ink cartridges alongside multipacks provides the best continuity for heavy drafting schedules. If you produce full-colour GIS maps and renders, stock up on complete 727 colour sets including grey (3WX15A) to maintain smooth tonal gradients across prints. Standard orders ship directly from local warehouses in Perth, Brisbane, Sydney, Melbourne, and Adelaide. Free delivery applies on all orders over $99.

Important buying tip for large format printing
When printing mixed technical files, monitor your grey 727 (3WX15A) ink level closely alongside matte black; the printer uses grey ink to smooth line transitions and balance neutral tones without over-saturating fine architectural details.
Frequently Asked Questions
Why does the HP DesignJet T920 use both matte black and grey ink cartridges?
Matte black delivers crisp, high-density line work on uncoated bond paper, while grey ink controls shading transitions and prevents colour cast when printing detailed CAD drawings and monochrome renders.
Can I mix 130ml standard and 300ml high-capacity 727/727B ink cartridges in the same printer?
Yes, the HP DesignJet T920 accepts individual 130ml and 300ml cartridges simultaneously across different colour slots, allowing you to run high-capacity 727B (3WX19A) matte black alongside standard 727 (B3P19A) colour cartridges.
What happens if a single colour cartridge runs out during a large format print job?
The printer pauses the current print job and prompts for a cartridge replacement without discarding the printed portion, protecting high-value media rolls from being wasted mid-print.
