EPSON AcuLaser C1900/AcuLaser C900 Revision B
Product Description Control Panel 64
1.4.5.4  Settings controlled by the mechanical controller, but 
requiring reading out and changing the values
 Amount of C Toner used/Amount of M Toner used/Amount of Y Toner used/
Amount of K Toner used:
Indicate the consumption amount, from 0 to 100% (in 2% increment), expressed as 
a counter value using the dot counter circuit. For the 1.5 k capacity toner, this 
value is same as above.
 Life counter of C Toner/Life Counter of M Toner/Life Counter of Y Toner/
Life Counter of K Toner:
The total number of printed pages after a new one is detected.
 Amount of Photoconductor Unit used
Indicate the consumption amount of the photoconductor unit, from 0 to 100% 
(in 2% increment).
 Amount of Transfer Belt used
Indicate the consumption amount of the transfer belt, from 0 to 100% 
(in 2% increment).
 Amount of Fuser Unit used
Indicate the consumption amount of the fuser unit, from 0 to 100% 
(in 2% increment). 
NOTE: Since the fuser unit does not support the new unit detecting function, the 
controller clears the counter.
 Normal paper second transfer voltage adjustment
Adjust the second transfer voltage determined by the picture stabilization control 
on normal papers.
 Thick paper second transfer voltage adjustment
Adjust the second transfer voltage determined by the picture stabilization control 
on thick papers.
 Transparency second transfer voltage adjustment
Adjust the second transfer voltage determined by the picture stabilization control 
on transparencies.
