Adjusting Doctor-To-Sleeve Gap - Toshiba FC-22 Manual

1.15 Adjusting Doctor-to-Sleeve Gap

Adjustment tool to use : Doctor-sleeve jig
Adjusting procedure :
(1) Remove the developer unit from the process-
ing unit (EPU), and then remove the devel-
oper unit cover and toner-scattering preven-
tion seal holder from the developer unit.
(2) Loosen the 2 screws for fixing the doctor blade
(M3), and insert the gauge "0.60" of the jig
into the gap between the developer sleeve and
the doctor blade to adjust the gap.
Fasten the screws for fixing the doctor blade
after adjusting.
(3) Insert the gauge "0.55" of the jig into the gap
between the sleeve and the doctor, and make
sure that the gauge can move smoothly in the
front rear direction. In addition, confirm
that the gauge "0.65" cannot be inserted into
the gap.
Note :
1. When confirming and adjusting the gap between the developer sleeve and the doctor blade, insert the
gauges into the gap after rotating the developer sleeve so that its marking faces the doctor blade.
2. While reinstalling the toner-scattering prevention seal holder, make the slide hooks inserted securely.
3. After reinstalling the toner-scattering prevention seal holder, make sure that each of the side mylar
sheets (one each on the front and rear) is between the 2 urethane rubber sheets.
4. While reinstalling the developer unit cover, make the latches fitted securely.
