PREVENTING THE “TONER LOW ” LAMP
FROM TURNING ON.
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (U.S. Version)
2.Genaral: Occasionally, the “Toner Low” lamp may go on although there is still toner in the
cartridge. This may be due to the “scrape off sheet”, which is affixed to the
supplementary toner feed in the toner hopper, rising too far up (reducing the angle of an
input lever) and causing the toner level in the hopper to drop.
3.Description: Because of strict quality control and thorough visual checks, this problem should not
occur in machines produced after November 1994. Some improvements have been
carried out in the shape and quality of the sheet and replacement should be carried out
on any machines produced previous to that date.

(No.8) as shown in Fig. 2, A.
(7) Draw the shafts and gears apart as shown in Fig. 2, B.
(Work can proceed without this being done, but there is a possibility that the shafts
and gears will come apart spontaneously later on)
(8) Peel off the “scrape-off sheet”, which is affixed to the supplementary toner feed, and
remove the shutter, as shown in Fig. 2, C.
(9) Peel the double sided tape off of the top of the toner hopper.
(Be careful not to allow any foreign particles to enter the toner hopper)

(11) Af fix the new sheet, being careful to match up A’, B’ on the sheet to the standard
A,B on the toner hopper.
(Press down firmly when affixing the sheet)
• As it is difficult to fix the front of the sheet to the convex portion of the screw unit
(No.17), it is preferable to affix the front of the sheet to the concave portion of the unit.
(In cases where the front of the sheet comes to the convex portion of the unit,
it is possible to remove the screws and gears and rotate the unit until the sheet
matches up with the concave portion)
(12) Affix the new shutter to the top of the toner hopper.
(Allow no foreign substances to fall in)
(13) Reinstall the gears and shafts removed in (11) and (7).
(Match up the toner gear 24 and the DV gear in the toner motor)
(14) Reconnect the toner hopper and toner holder which were disconnected in (6)
(Insert the toner shaft 22 into the toner bracket 1 , and then reinsert the screws)

shown at the back of Fig. 4,B
• B e careful not to put the compression stopper shown in diagram 4,C onto the parts
shown in Fig. 1,D
(16) Reversing the steps described in (3), fix the cover
