Frequently Asked Questions

Will the C4127A toner cartridge void my HP printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, HP cannot void your printer warranty solely because you installed a remanufactured (non-OEM) toner cartridge. The C4127A is designed to drop in as a direct replacement for the OEM part.

What page yield should I expect from the C4127A?
The C4127A toner cartridge is rated for approximately 5000 pages at standard 5% page coverage (ISO/IEC test conditions). That puts it in the high-volume category - a good fit for offices that print steadily through the week.

Which printers use the C4127A?
The C4127A fits a range of HP models (HP LaserJet series), including the LASERJET 4000, LASERJET 4000 N, LASERJET 4000 T. The full compatibility list is in the Compatible Printers section above - check your printer model there before ordering.

How much will I save versus a genuine HP C4127A?
At $48.95, the Castle Ink C4127A is about 51% less than the typical OEM retail price of $99.94. For users printing regularly, that saving compounds quickly across replacements.

When will my C4127A order ship?
Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping on orders over $50. Most U.S. customers receive their order in 2-3 business days. Expedited shipping is available at checkout.
