A. The original set in the paper feed tray is pressed against the paper feed roller by the paper up/

down plate, and then struck against the registration roller by the paper feed roller and the feed

roller to form a loop. The amount of the loop is controlled according to a value registered by

the timer after the leading edge of the original turns on the PS308 (Original registration sen-

sor).

B. After the loop is formed at the registration roller section, the M301 (Original feed motor) rotates

backward and the M302 (Original conveyance motor) re-feeds paper. The original is scanned at

the slit glass section according to a value registered by the timer after the leading edge of the

original turns on the PS 309 (Original conveyance sensor). At this time, if there are originals in

the tray, the next original is pre-fed according to a value registered by the timer after the trail-

ing edge of the preceding original turns off the PS308 (Original registration sensor). When the

trailing edge of the last original turns off the PS309 (Original conveyance sensor), the M301

goes off. When the PS302 (Original exit sensor) detects the trailing edge of the last original, the

M302 goes off to finish the scanning of the original.

1.2.2 Double sided original mode

A. In the double sided original mode, the original is reversed and its back side is scanned first,

and then the front side is scanned before being straight ejected. Copying originals in their

scanned order may cause the copied sheets to get out of their specified pagination. To avoid

this, image processing is used for page alignment. The original set in the paper feed tray is

pressed against the paper feed roller by the paper up/down plate, and then struck against the

registration roller by the paper feed roller and the feed roller to form a loop. The amount of the

loop is controlled according to a value registered by the timer after the leading edge of the

original turns on the PS308 (Original registration sensor). After the loop is formed at the regis-

tration roller section, the M301 (Original feed motor) rotates backward to re-feed paper. Upon

backward rotation of the M301, the M303 (Original reverse motor) also rotates backward to

open the reverse guide and convey the original to the reverse roller. The reverse roller can

release pressure through the SD302 (Roller pressure solenoid). It turns on the SD302 (Press-

ing by reverse roller) according to the value registered by the timer after the PS308 is turned

B. According to the value registered by the timer after the PS308 (Original registration sensor)

detects the trailing edge of the original, the M302 (Original conveyance motor) and the M303

(Original reverse motor) rotate forward to reverse the original and convey the back side to the

slit glass section. The reverse guide is closed by the forward rotation of the M303 and the flap-

per[4] is opened by the rigidity of the original. As a result, the original is guided to the convey-

ance roller. At this time, if there is a succeeding original in the tray, it is pre-fed according to

the value registered by the timer after the trailing edge of the preceding original turns off the

PS308 (Original registration sensor).

C. According to a value registered by the timer after the leading edge of the original turns on the

PS 309 (Original conveyance sensor), the back side of the original is scanned at the slit glass

section. At this time, the SD301 (Paper exit solenoid) is turned on to close the paper exit guide,

and a original the back side of which has been scanned is conveyed to the reverse roller. The

SD301 is turned on according to a value registered by the timer after the leading edge of the

original turns on the PS309. Paper conveyed to the reverse roller switches back and conveys

again an original to the conveyance roller, thus replacing the back side of the original with its

front side. Since the leading and trailing edges of an original larger than B5R is overlapped

each other while in switching back at this reversal section, the SD302 (Roller pressure sole-

noid) is turned off to release the pressure of the reverse roller.

left open and the original the front of which has been scanned is conveyed to the paper exit

roller to be exited. While the back of the original is being scanned, the SD301 goes off accord-

1.2.3 Mixed original mode and Z-folded original mode

The mixed original mode supports both the same series original and the different series original. The oper-

ation of the original conveyance in the mixed original mode is the same as that of the normal double sided

original mode, regardless of a single sided mode or double sided mode.

Although the detection of original size in the normal mode is made at the time when the original is set in

the paper feed tray, the size detection in the mixed original mode, however, is made based on the length of

time when the original passes through the PS308 (Original registration sensor) while the original is being

sent from the paper feed tray to the reverse roller. The original detection like this is applicable to all origi-

nals.

In the Z-folded original mode, the same detection operation as that for the mixed original sizes mode is

made only on the first original to determine the original size. However, the normal operation of original con-

veyance is made for originals on and after the 2nd original.

1.2.4 Original size detection

A. Normal copy mode

(1) Main scanning direction

Detected by the value of resistance of the VR301 (Original size VR) that is interlocked with the posi-

tion of the guide plate above the paper feed tray.

(2) Sub-scanning direction

Detected by the combination of the PS305 (Original size sensor /1) and the PS306 (Original size sen-

sor 2/) when they are turned on and off.

B. Mixed original mode and Z-folded original mode

(1) Main scanning direction

The width of the largest original of the mixed original sizes is detected by the value of resistance of the

VR301 (Original size VR) that is interlocked with the position of the guide plate above the paper feed

tray.

(2) Sub-scanning direction

Detection is made based on the length of time when the original passes through the PS308 (Original

registration sensor).

1.2.6 Control of the verification stamp for FAX

A. Operation of the verification stamp for FAX

In the FAX mode, a stamp showing that the original has been scanned is affixed on the original face

that has been scanned (for the double sided original mode, a stamp is affixed on front side only). The

stamp is driven by the SD303 (Stamp solenoid) and stamping is made when the original passes

through the paper exit roller. At this time, the M302 (Original conveyance motor) is turned off tempo-

rarily to stop the original.

How to use this catalog

This parts catalog includes illustrations and part numbers for all replacement parts and assemblies used in this model.

Model-specific parts are identified in the illustrations with reference numbers. Use the reference number to locate the corresponding part number on the facing page.

Common hardware items, such as screws, nuts, washers, and pins, are identified in the illustrations with reference letters. Use the reference letter to locate the corresponding part number on the hardware listing in the lower right hand corner of the facing page.

If you know a part number, but don’t know where the part is used, use the numerical index to determine the page number and reference number for that part. Because some common parts are used in several places, there may be more than one entry. Refer to the illustrations to see where the part may be used.

If you know a part’s description, but don’t know where to look to find the part number, use the alphabetical index to determine likely page and reference numbers. Then look at the illustrations to determine that you have identified the correct part. Locate the part number using the listing on the opposite page.

Retail pricing that appears with the numerical index, while valid when this catalog was printed, is subject to change without notice. The prices are only suggested prices and are provided only for reference. Dealers may determine their own selling prices. For up-to-date pricing, refer to current Konica price lists or contact the Konica Parts Distribution Center.

How to order parts

Use standard Konica parts ordering procedures to obtain these parts. For ordering options, contact Konica’s Parts Distribution Center.

When ordering parts, be sure to specify part numbers exactly as listed in this catalog.

NOTE: Electrical parts may include previously used components.
