IMPORTANT SAFETY NOTICES

PREVENTION OF PHYS ICAL INJURY

1. Before disassembling or asse mblin g pa rts of the print er and pe riph erals,
make sure that the power cord is unplu gged .

2. The wall outlet should be near the copier an d easily accessible.

3. If any adjustment or operat ion check ha s to be made with exterior covers
off or open while the main switch is turned on, kee p ha nds away from
electrified or mechanically drive n comp on ents.

HEALTH SAFETY CONDITIONS

1. If you get ink in your eyes by accident, try to remove with eye drops or
flush with water as first aid. If unsuccessful, get medical attent ion.

2. If you ingest ink by accident, induce vomiting by sticking finger down
throat or by giving soapy or strong salty water to drink.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The printer and its peripherals must be installed and mainta ine d by a
customer service represen tative who has completed the training course
on those models.

SAFETY AND ECOLOGICAL NOTES FOR DISP OS AL

1. Dispose of replaced parts in acco rda nce with local regulations.

2. Used ink and master should be disp ose d of in an environmentally safe
manner and in accordance wit h loca l regu lat ions.

– CAUTION –

The RAM pack has a lithium battery which can explode if handled
incorrectly. Replace only with same RAM pa ck. Do not recharge or burn
this battery. Used RAM packs must be handled in accordance with local
regulations.

2.1 OVERALL

A book type scanner is used for the #C218/#C219 mod els. There are 2
modes for scanning origina ls.
Platen Cover Mode: The original is placed on the exposu re glass, and the
scanner motor drives the scanner to scan the original.
ADF Mode: When an optional Docu men t Fee de r is installed, the original is
fed onto the exposure gla ss. The scann er move s 24 mm away from the CCD
and remains still as it scans the original. The scanner comes back to the
home position when the scanning is finished.

level. The standard white data are used to corre ct dist ortion. The scanner is
at its home position when it rea ds th e white level.

In the ADF mode, as the scanner move s 24 mm, th e CCD read s the wh ite

[Front Side]

[D]

[C]

[F]

[Rear Side]

[A]

[G]

A stepper motor is used fo r the scann er motor [A] to drive the scanners. The
first scanner [B], which consist s of th e exp osu re lamp and the first mirror, is
driven by the first scanner belt [F]. The seco nd scann er [C] , which consists of
the second and the th ird mirror, is driven by the second scanner belt [D] . Bo th
scanners move along the gu ide rails.

The timing belt [G] moves t he secon d scanner at half the velocity of the first
scanner. This is to maintain the focal distance between th e orig inal and the
lens during scanning.

The scanner home position is detected by the home positio n sensor [E]. In
the Platen Cover Mode, the scanner scans the original on the exposure glass
for the full A3 lengt h, then returns until the scann er ho me po sitio n sensor is
activated. In the ADF Mod e, the scanner moves 24 mm backwards (away
from the CCD), to scan the original which is fed by the ADF. When the
master making process is finishe d and the ADF motor stops, the scanner
goes back to the home position.

2.3 PLATEN COVER POSITI ON DETECTION

[B]

[A]

When the platen cover is opene d ab ou t 25 deg rees, the Platen Cover
Position Sensor [A] is deactiva ted. When this sensor is deactivate d, the
Original Sensor [B] is able to det ect the origin al on the expo sure glass.

When the Platen Cover Position Sensor is deactivat ed and the Origin al
Sensor detects no original on the expo sure glass, the machin e indicates
"SET THE ORIGINALS" on the operat ion displa y. This is t o pre ven t wast ing
of the master that wo uld occur whe n the Master Making key is pressed with
no original placed on the exposure glass.

When the original is placed on the expo sure glass and the Master Making
key is pressed with the pla te n cover opened more than 25 degrees (a s the
Platen Cover Position Senso r is deact ivat ed ), th e shadow erase function is
enabled.

SCANNER 15 July 1994

Notes regarding the shadow erase function:

• Margins of 1 mm, 0.02" on all four sides of the original will be erased. The

width of the margins will change depending on the rep rod uction ratios.

• Shadows near the book edge might not be erased complet ely.

• If the shape of the originals are as sho wn be low, shadows might appear

on the prints. In this case, make the master with the platen cover clo sed .

T3: When the scanner has move d 20 millimeters from its home position (17

mm for the C219 model), the master starts to be fed. When the maste r
has been fed 0.9 millimeters (1.0 mm for the C219 model), the thermal
head starts plotting on the mast er.

The leading edge is zero when the sca nner is 12 millimet ers from its
home position. The leading edge margin can be adjusted within the rang e
of 4 to 10 millimeters by SP mode No.33.

T4: When the master has been fed 38 millimeters (41 mm for C219 models),

the reverse roller magnetic clutch tu rns of f. Then the master is fed 5
millimeters more and the master feed clamper solenoid is de-energized to
close the master clamper. The master is fed in the same way as in #C210
models. The original transp ort and the maste r f eed mot ors speed up once
the master plotting is done. The master feeding lengths for plotting are:

For #C218 models
412 millimeters: A3/DLT dru m
204 millimeters: A4/LT dru m
For #C219 models
355 millimeters: for both B4 and LG drums

T5: When the scanner has scanned the fu ll scanning length (the sa me len gth

as the master feeding length), the scanner motor starts its reve rse
rotation to bring back th e scanner to the home position.

T6: The master feed mot or stops when the master has been fe d 53 4.4

The cutter motor st ops wh en the cutt er ho lder goes back to the home

When the right cutter switch is activated, the drum starts rotatin g to go
back to its home position . Whe n the left cutter switch is activa te d (when
the cutter comes back to it s home position), the master fe ed motor turns
on again to feed the master 40 millimeters.

When the drum release lever [A] in fro nt of th e mach ine is raised, the
connector [B] is push ed away fro m t he drum by th e bra cket [C] through the
link [D], and is disconnected. The bracke t [C] also pu she s the drum lock leve r
[F] to release the dru m lock allowing the drum to be removed. Wh ile th e drum
is away from its home position, the drum lock solenoid [G] is energized and
the stopper [H] locks the link [D] to preven t th e dru m from be ing pulle d out.
The solenoid is de-energized when the drum stops at th e ho me po sitio n
(when the 1st drum position senso r is act uated).

2.4 THERMAL HEAD TEST

This function is used to determine which printer component is causing an
image problem on the master.

In this mode, the background patt ern that is printed covers the entire sheet of
paper.

Procedure

1. Place paper on the paper table.

NOTE: To reduce th erma l hea d loa d, use th e smalle st pape r size possib le,

i.e. the smallest size on which the area with the image proble m can
be printed.

2. Access SP mode.

3. Input No. 90 and press the En ter key.

NOTE: The fa cto ry setting is pattern No. 7. If ne cessa ry, input another

background pattern with the Number keys.

4. Press the Master Making key (an origin al is not nece ssary).

5. Make prints and check the image.

Assessment

If the pattern image is normal, a Pa rt A comp on ent is def ective.
If the pattern image is abnormal, a Pa rt B component is defective.

NOTES:1. The VT master can be installed in the C218/ C219 models.

However, a weak image (sometimes a blank image) will appear.
This is because the VT II master is more sensitive tha n the VT
master.

2. The modified clamper an d th e tetron screen must be installed.

3. For the U.S. version of th e machine, the modified Drum Unit Ra il
End must be installed (for safe ty sta nd ard reasons).

4. Ink leakage may occur at th e trailing edge.

5. The A3 size print area for the C218 model is long er th an tha t of
