Print cartridge memory chip
The print cartridge memory chip is a non-volatile memory device built into the print cartridge. It
stores information about the cartridge. The DC controller PCA reads and writes memory data to
the memory chip to monitor the print cartridge usage and condition. The DC controller PCA
reads and writes to the memory chip at specific times. If the read-write process fails four times in
a row, the DC controller PCA detects a print cartridge memory failure and a 10.00.00 SUPPLIES
MEMORY ERROR error message appears on the control-panel display (see “Numerical printer
messages” on page 274).
