NOTE 1. To meet the safety standard, the fuse on the board has been changed (11070391 → 11070752) from the first

production machines. As a result, the part number of the ADF main control board has also been changed. (The difference between A0285811 and A0285805 is the fuse only.)

NOTE 2. To enable the use of F4 size paper (8

1/2 x 13"), the ROM’s on the main board, operation ROM board, and paper feed

control board have been changed. (Their part numbers have not been changed. For details, refer to RTB No. 1. ) To enable the use of the same function on the ADF (original size detection), the ROM has been changed from the March ’92 production. (5 machines of the first production use the old type ROM : A0285851.) The part number of the board is still the same (A0285805 → A).

DETAILS OF MODIFICATION

It was found that the bearing on the front side of the original exit roller (A0 28 7498) b rea ks or the roller sha ft wears out du e to too high tension of the drive belt . This may occur after making 800,000 copies (in worst case) and cause original misfeeds at the exit area.

To control the drive belt tension properly, a belt tightener has been added as shown below. Due to this, the drive belt has been lengthe ne d. The pulle y (A 0287 635) an d E-rin g (07 2000 40 E) are still used in the different locations as shown.

Note: As a temporary method in the production, the tigh tener spring which has stronger t ension than that of the prope r

tightener spring (A112 76 20 ) has be en used . The proper tightener spring ha s bee n use d from November 1993 production (S/N-620311 00 01).

First Transport Sensor

Information for Ricoh model (Ricoh FT9101 ) star ts from thi s bull eti n. MB no. 1 to no. 11 are for the Ge ste tner and nashuatec models only.

To minimize original smearing or jams in the RDH mode, the pulley, which drive s the entrance turn roller, and the right turn guide plate have been changed . Deta ils of th e cha nges are as follows.

NOTE: This improvement is more effective with the new RDH ROM (refer to RTB-017).

1. In the RDH the original is stopped once at the ent ran ce of the inte rmediate transport section as soo n as the first tran spo rt sensor detects it. At this time, while the first and secon d relay rollers stop immediately, the entrance turn roller still turns because of a one-way clutch built-in the roller’s pulle y. As a result , the orig ina l rubs ag ain st th e first relay roller and this will cause smearing on the reverse of orig ina ls after many original recirculations. This ma y also cau se orig inal jams if the original stop position is too late.

To prevent this symptom, the one -way clut ch in th e en tra nce turn roller pulley has been removed, and th e pu lley is fixed on th e roller shaft with two headle ss set screws. The one-way clutch was used to make it easier to pull out the jammed origina l stopped between the rollers. Due to this mo dif ication, the removal of such a jam slightly becomes harder but it remains no problem.

CAUTION: As a special hard material is used for the roller’s shaft, be sure to tighten the set screws firmly t o prevent

the pulley from slipping on the shaft . The remo val of the pulle y is no prob lem eve n whe n th e set scre ws are tightened strongly due to the hard mate rial of the shaf t.

2. When the original enters the right turn ro ller, the le ading edge tends to hit the driven rollers as shown below. If the original is stopped there, th e second relay roller rubs the original beca use it still turns. This will make smearing on the reverse of the original, an d it be come s visible after many original recirculatio ns.

To prevent this, the guid e strips have been added to the right turn guide plate, so th at the origin al leading edge smoothly enters between the right turn rolle r and its driven roller.

Angle for the roller’s free rotation

When an original stops in front the right turn rolle r, th e trailing edge of the previousely fed original is still caught with the right turn roller as shown below. Due to a one-way clutch built-in th e righ t turn rolle r’s p ulle y, th e roller can still turn to feed the original even after the original feed moto r stops.

As a side effect of the RDH ROM modification (refer to RTB-01 7), the trailin g edge of orig ina ls ten ds to be caugh t with the right turn roller because th e orig inal feed motor stops earlier than old type. This might cause original jams, especially wh en 11" x 81/2" or 14" x 81/2" originals are used (their short edges are longer than that of A4 size). Also, as the original stop timing in the intermediate tran spo rt fo r t he last original is slightly earlier than usual in the simplex orig ina ls to du ple x copy mode, the last original tends to be delayed to be transpo rted onto the exposure glass. Thus, creating an improper leadin g edge registration for its co py. (This does not occu r with A4 origin als, but might occur with 11" x 81/2" or 14" x 81/2" origi- nals.)

NOTE: These symptoms do no t occu r wh en the tran sport belt is replaced at the PM intervals. If the friction between

originals and the transport be lt be come s less, the problems will occur.

To increase the tolera nce for th e modification of MB no. 13 (the right tu rn pre ssure roller change), the right turn roller ha s been changed as shown below.

The one of the rubber rollers (the non-op eration side) has been changed to a meta l f lywhe el. This allows the right turn roller to rotate more smoothly after the origina l fee d mot o r sto ps. For the application to the field ma chin es, the change of the right turn pressure roller is effective enough.

To increase the durability, the follo wing chan ge s have been mad e:

1) The dry bearings have been changed to ball bearings. Due to this, the portions of the air duct which sup po rt th e bearin gs ha ve been enlarged. Also, to prevent th e shu tter spring boss from touching the new ball bearing, a groove has been made on the boss. (Therefore, th e air duct, two ball bearings, and shutt er spring boss can be changed only as a set.)

2) To prevent the shaft of the shutter spring boss from wearing out, the material of the solenoid link has been chan ge d fro m me ta l to plastic. The thickness has also been chan ged from 1 mm to 2.5 mm.

CAUTION : 1. Even after using the new pa rts, the shutter solenoid position mu st be ch ecke d every 2,000,000 copies to

prevent original feed jams. If necessary, adjust the position according to th e service manual.

2. When the solenoid is installed, fix it so tha t the link do es not interfere with the shutter spring bo ss as shown .

For the customers who use 11" x 81/2" o r 14" x 81/2" originals, a slot had to be made to sto p the original end plate at the 81/2 inch position. (Refer to RTB-012 for the Gest et ner/nashuatec models or page 1-14 of the field service manual for the Ricoh model.) If the slot is made, an opera to r may set th e orig ina l e nd plat e at the wrong posit ion (b eca use the A4 and 81/2 inch positions are very close) and this will cause original feed jams.

To improve this, the end plate stopper has been changed as shown below.

DETAILS OF MODIFICATION

It was found that the shaft of th e inve rte r e ntrance roller might wear out or that the rolle r’s bea ring s mig ht brea k when the tension of its d rive belt is t oo string . Although the tension is determine d by a spring, too much tension is applied when the screw in the lowe r right side (see illustration) is tighte ne d first .

To prevent this, the screw securing the lower side of the inverter idler pla te (P /N-A 02 8772 7) ha s been cha ng ed to a stud (Return Lever Pin: P/N-5410129 1). The other screw has also be en change d to a golden (zinc plated) screw to identify it as an adjusting point . The inverter idler plate is now fixed with only o ne scre w and the stud works as a guide for the pla te.

MODIFICATION BULLETIN NO. 18 PAGE 3 OF 3

ISSUED ON: April 15, ’94

To increase the durability of the shaft of the inverte r ent rance roller, its material has been chan ge d to a harder metal. At the same time, the end of the sha ft , to which the drive pulley is installed, has be en leng thened by 2mm. This makes the flat part of the shaft visible so that the pulley can be prope rly positioned before tightenin g the two headless set screws.

CAUTION: With the old inverter ent ran ce roller, the pulley just meets the end of the rolle r’s sh af t, but with th e ne w one 2mm

from the end of the shaft must be seen when the pulley is installed as sho wn below.

To make the removal of the inverte r ent ran ce roller easier, the bushing plate (P/N-A0287538), which includes a ball bearing, has been changed to a norma l ball be arin g (P/N-07413506). (The screw securing the bushing plate was hard to access. ) Due to this, the spacer of 1mm thickness (P/N-A0287878) has be en ch ange d to another of 2mm thickness (P/N-A0287744).

NOTE: At the same time with these mo dif icat ions (the same cut-in serial numbers), the proper tightener spring

(P/N-A1127620) for the origin al exit roller ha s been use d. Before this, a tightener spring which has stro ng er te nsion had been used as a temporary method in the pro duction. (Even with the stronger tightene r spring, there was no problem for the performance. But it has been changed to in crea se tolerance.)

If was found on the production line tha t abno rmal lea din g ed ge registration suddenly occurs during a copy run . This was because of part variation of the main board. All main boards use d on the production machines and used as service parts have been teste d, and we have been using only the main bo ard s wh ich do not cause such a problem. Recently, we have found th at this problem is cured by replacing resistor R236 on the main board with # 16303102.

If this problem occurs in the field, the lead ing edg e reg istra tio n will sometimes differ 7 to 8 mm during a copy run. If this is found, replace th e main board.

ISSUED ON: November 30, ’94

DETAILS OF MODIFICATION

The size of originals set in the RDH can be detecte d based on the positions of the side fences and original stopper (the end fence). Since the widt hs of 81/2" x 14" and B4 originals are close, 81/2" x 14" originals can be distin gu ishe d by th e original stopper position. When the origina l stop per is set at the 81/2 inch position, the original length sensor is activated by the end fe nce gear which moves along with the origin al sto pp er.

However, the area on the gear wh ere light from the original length senso r is reflected varies from one machine to another due to part variation. Very rarely, the orig ina l leng th senso r sometimes is not activated properly. If this occurs and 81/2" x 14" originals are used some originals are rand omly fe d ou t up-side down because the RDH carries out the original transportat ion wit h th e timin g for B4 originals and some originals are no t inve rte d in th e reversing section properly. Due to the same reaso n, blan k copie s or copie s wit h abno rmal lea ding edge registrations are made.

NOTE: 1. This problem does not alwa ys occur eve n in th e problem machine. The original stopp er po sitio n sligh tly

varies each time when it is set.

2. This problem does not occur when 81/ 2 " x 11" origin als are used . Such origin als can be distinguished from the other size originals by only the position of the side fence s.

To ensure that the original len gth sen sor is a ctiva te d pro perly, th e orig ina l le ngth sensor actuator has been adhered on the end plate front guid e as sho wn on the following page.
