The shape of the CR Scale has been changed for Artisan 835/837/725/
730/PX820FWD/TX820FWD/PX830FWD/PX720WD/TX720WD/
PX730WD/TX730WD, therefore, see
"8.3.2.4 CR Scale" (p.270) for
disassembly/reassembly procedures. In addition, some printers
among Artisan 810/710/PX810FW/TX810FW/PX710W/TX710W use
the same CR Scale as for Artisan 835/837/725/730/PX820FWD/
TX820FWD/PX830FWD/PX720WD/TX720WD/PX730WD/
TX730WD, so see
"8.3.2.4 CR Scale" (p.270) in such a case.
