[PM Counter Display] 7803
(Sheets or Rotations, Unit, [Color])
Dev.: Development Unit, PF: Paper Feed Rollers, Fusing: Fusing Unit,
Transfer: Transfer Unit
Displays the value given by the following formula:
(Current revolution ÷ Target revolution) × 100, where “Current revolution” is the values of SP7-
803-18 through 27 and “Target revolution” is the fixed values. This shows how much of the unit’s
expected lifetime has been used up.
The R% counter is based on rotations, not prints. If the number of rotations reaches the limit, the
machine enters the end condition for that unit. If the print count lifetime is reached first, the
machine also enters the end condition, even though the R% counter is still less than 100%.
