E025-0x51 due to the continuous paper passing of entire solid
image whose size is A3 or larger.
[Symptom]
E025-0 x51 might occur if the size of media is A3 or larger (A3, 12X18, 13X19, SRA3 etc.) when continuous paper passing of
entire solid image is performed.
- The Developing Toner Density Sensor (Y) consecutively detected a value that was DENS value -6% or less. (TD ratio: 3% or
less)
(x=1:Y , 2:M , 3:C , 4:Bk)
[Cause]
Whole amount of toner in the Hopper will be consumed by the continuous paper passing of 600 entire solid images whose size
is A3 or larger after that "Replace the toner container" is display on the status bar of UI screen.
If the continuous paper passing is kept on performing, "Replace the toner container" is display on the UI screen few seconds after
the detection for that there is no toner in Sub Hopper. Then the feeding paper is forcibly stopped.
At the time, if the density of solid image is kept being higher than expected density, the toner in the Developing Assembly becomes
too small in amount before the forced stopping of paper feeding. That results in the above error.
[Service work]
1) Remove the unfinished papers in the devices (main body+ pick-up/ delivery related options).
2) Insert new toner bottle.
3) Turn OFF/ON the main power supply and wait few minutes until the Hopper is replenished with toner.
[Reference] Since the Hopper was empty, so the toner bottle gets empty before the Hopper becomes full with tonner. Replacement
for new tonner bottle is recommended.
4) Output around 10 sheets which are A3 size or larger than LDR size, and duplex white solid image.
This operation restores the tonner amount in the Developing Assembly.
[CAUTION] When the tonner amount in the Developing Assembly does not be restored and the same error occurs during the
operation, turn OFF/ON the main power supply and repeat the step 4).
5) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
