E026-0x01 Error Code
E026-0x01 Error Code / Message [Remaining toner is low.] /
Toner scattering inside machine.
E026-0x01 can be displayed when the
toner concentration does not return to a normal level after replacement of the
toner bottle and 5-time toner recovery sessions following the detection of toner
In the field, this symptom occurred because the toner shutter in
the developing assembly was not open completely and the toner was not supplied
from the toner bottle to the developing assembly.Workaround :
Before installing the developing assembly into the host machine, be sure
to slide and fix the toner shutter so as to cover the opening for toner. Then,
install the toner bottle.
Points to Keep in Mind When Fitting the Developing
- Before starting the work, check to be sure that the
shutter  is forced in the direction of the arrow. If not, move it in the
direction of the arrow until it butts against the shutter . If it is not
fully butted against the shutter, you may not be able to fit the toner cartridge
- When fixing the developing unit using a screw , be sure
to force the casing of the developing unit in the direction of the arrow as you
tighten the screw. After tightening the screw, try pushing the casing of the
developing unit in the direction of the arrow to make sure that there is play of
about 1.5 to 2 mm. If there is no play, remove the screw , and tighten it
while forcing the casing of the developing unit in the direction of the
This step is performed so that the screw base will not ride over
the developing cartridge guide plate . If you tighten the screw while it
rides over the guide plate, the spatial relationship between the photosensitive
drum and the developing cylinder will be wrong, causing blank output.
