Epson Aculaser C1100 Series Instruction Manual page 160

If a consumable product reaches the end of its service life, the
printer stops printing and displays the following messages on the
LCD panel or the window of EPSON Status Monitor 3. When this
happens, the printer cannot resume printing until you replace the
depleted consumable products.
LCD Panel Message
Replace Toner uuuu*
Replace Photocondctr
* The letters C, M, Y, and K appear in this position, indicating the color of the
toner to be replaced. For example, the message Y Toner Low means that
the amount of toner remaining in the yellow toner cartridge is low.
Note:
Messages appear for one consumable product at a time. After replacing
a consumable product, check the LCD panel for replacement messages
for other consumable products.
Even if Replace Photocondctr is displayed on the LCD panel,
you can continue to print for a short time by pressing the N
Start/Stop button on the control panel. The message on the LCD
panel changes from Replace Photocondctr to Worn
Photoconductor.
Note:
❏ Print quality cannot be guaranteed when printing with a worn
consumable product. If print quality is not what you expected,
replace the consumable product.
❏ The printer stops printing if printing with a worn consumable
product might damage the printer. If the printer stops printing,
replace the consumable product.
