Toner Cartridges, Maintenance Kits and Parts

One Item
The SF 535E uses a single toner cartridge, CTC TD-R510P. CTC TD-R510P yields 3000 pages.
The CTC TD-R510P cartridge has an approximate yield of 3000 pages.
A "Supply Problem" message on the SF 535E 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 CTC TD-R510P will clear it.
