Common questions
Will this replacement for the HP 42X void my printer's warranty?

No. Under Canadian consumer-protection law, a manufacturer can't void your printer's warranty just because you used a compatible cartridge, the same way a non-OEM oil filter can't void a car warranty. Your printer stays protected.

Are remanufactured cartridges covered by the warranty?

Yes. Both new compatible and professionally remanufactured cartridges carry the same Limited Lifetime Warranty. Only cartridges that have been refilled or emptied through normal use, or damaged through misuse, are excluded.

What if my toner ever damages my printer?

You're covered. If an authorized technician documents an Elevate Imaging toner as the sole cause of damage to the printer it was designed for, Elevate Imaging covers the repair, replacement, or reimbursement, and you file the claim directly through us.
