Frequently Asked Questions
The SF 7750 uses SHR SF-770LT1 (SHR SF770LT1) and SHR SF-770NT1 (SHR SF770NT1) toner cartridges. SHR SF-770LT1 yields 4200 pages; SHR SF-770NT1 yields 4200 pages.
The SHR SF-770LT1 cartridge has an approximate yield of 4200 pages.
A "Supply Problem" message on the SF 7750 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement SHR SF-770LT1 will clear it.
