Black Genuine Developer Standard Yield, 50,000 pages
The EP4290 uses KNI PCUA946483 and KNI 946483 toner cartridges. KNI 946483 yields 6250 pages.
The KNI 946483 cartridge has an approximate yield of 6250 pages.
A "Supply Problem" message on the EP4290 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 KNI 946483 will clear it.
