Displays the estimated usage rate (0 to 100%) and remaining days (255 to 0 days) of the PM items against the PM yield, which are based on calculations using the page counter and running distance.
[A]: Number buttons. Pressing a number button opens a sub menu.
[B]: Descriptions. The # mark denotes a “unit” (not an individual item)
[C]: Displays the estimated usage rate (0 to 100%)
[D]: Displays the estimated remaining days (255 to 0 days)
[E]: Press [No] to reset the selected PM counter to "0".
Calculation of Estimated remaining days (255 to 0 days) and Estimated usage ratio (0 to 100%)
Calculation of estimated remaining days (255 to 0 days)
Displays either the page counter (SP7-951-XXX) or the running distance (SP7-952-XXX), whichever is smaller. Note that parts such as rollers always show the page counter value, because running distance is not counted.
Remaining days by page counter (SP7-951-XXX) = (A – B) / C
A: Standard end value as pages (SP7-623-xxx)
B: PM page counter (SP7-621-xxx)
C: Average PM page counter per day = PM page counter (SP7-621-xxx)/Number of days since last replacement
Remaining days by running distance (SP7-952-XXX) = (A – B) / C
A: Standard end value as distance (SP7-940-xxx)
B: PM distance counter (SP7-944-xxx)
C: Average distance per day = PM distance counter (SP7-944-xxx) /Number of days since last replacement
Calculation of estimated usage rate (0 to 100%)
Displays either the page counter (SP7-954-xxx) and running distance (SP7-942-xxx), whichever is larger. Note that parts such as rollers always show the page counter value, because running distance is not counted.
Estimated usage ratio % (by Page counter) is calculated as follows.
Current page counter value <SP7-621-xxx> / Standard page end value <SP7-623-xxx> x 100
Estimated usage ratio % (by Running distance) is calculated as follows.
Current distance <SP7-944-xxx> / Standard distance end value <SP7-940-xxx> x 100
