Frequently Asked Questions

Will the CF237X 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 compatible (non-OEM) toner cartridge. The CF237X is designed to drop in as a direct replacement for the OEM part.

What page yield should I expect from the CF237X?
The CF237X toner cartridge is rated for approximately 25000 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.

How do I confirm the CF237X fits my printer?
Match the cartridge number printed on your current HP cartridge to ""CF237X"" - if they match, this is the right replacement. You can also check the Compatible Printers section above, or contact our U.S.-based support team if you're unsure.

How much will I save versus a genuine HP CF237X?
At $185.95, the Castle Ink CF237X is about 38% less than the typical OEM retail price of $299.95. For users printing regularly, that saving compounds quickly across replacements.

When will my CF237X 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.
