PERATING PRINCIPLES Electrical Circuit Operating Principles
3.1 C616 PSB/PSE Board the PSB/PSE Board of Stylus C67/C68/D68, the simulated oscillating stimulation back converter circuit method is used, and it supplies +42 VDC to the drive line. e application of the output voltage is described below.
C616PSB Board: 100-120V
C616PSE Board: 220-240V
voltage input from AC inlet first goes through filter circuit that removes high quency components and is then converted to DC voltage via the rectifier circuit and smoothing circuit. DC voltage is then led to the switching circuit and FET Q1
eforms the switching operation. By the switching operation of the primary cuit,+42VDC is generated and stabilized at the secondary circuit.

Be careful to avoid electric shocks when checking the electrical circuit boards (C616 MAIN, PSE and B circuit boards) while the power is turned on.Touching an FET, transistor or heat sink with one hand while touching a metal part of the mechanism with the other hand could result in an electric shock, so carefully avoid this.After initial filling of ink has been repeated several times, immediate moving or tilting of the printer could result in leaking of ink that has not been completely absorbed by the Waste Ink Pad. When initial filling of ink has been repeated several times, check the ink remaining in the tip of the Waste Ink Tube and the waste ink not absorbed by the Waste Ink Pad before moving the printer.
Disassembly and reassembly of parts is often required when identifying the causes of problems. The parts should be disassembled and re-assembled correctly while referring to DISASSEMBLY/ASSEMBLY (p35) so that the operation and status of each check item can be correctly verified.Some individual part and units may require adjustment once they are removed or replaced. If removing or replacing parts which have specific instructions for adjustment included in DISASSEMBLY/ASSEMBLY (p35), be sure to make these adjustments after repairing the problem location.

2 Caution regarding Assembling/Disassembling the Printer Mechanism, and How to Ensure of uality on Re-assembled Product current low end models, we’ve basically forbidden to remove Housing, Lower from
inter mechanism in your repair. This is because there is a possibility of main frame formation when a part (such as Ink system) is removed from Printer mechanism thout Housing, Lower. r this reason, if you want to replace Ink system/PF motor, we recommend to replace th new Printer mechanism with Housing, Lower. On these models, you have to
ove Housing, Lower from printer mechanism when replacing Waste Ink Pad with a w one. erefore, we clarify caution regarding assembling/disassembling of the printer chanism without Housing, Lower, and how to ensure of quality on repaired products this section.
aution regarding assembling/disassembling of the printer mechanism]
Main frame
Control of assembled standard position.
[Reason]The assembled accuracy of each part composed of Printer mechanism is based on Housing, Lower.
[Service treatment]Confirm that there is no gap between main frame and Housing, Lower.
[Reference]To ensure the assembled accuracy, you have to control the assembled standard position of main frame against X/Y/Z-axis direction.
[X-axis direction]- Make sure that main frame is correctly placed on the groove of Housing,
Lower.- Make sure that there is no gap between main frame and Housing, Lower.
[Y-axis direction]Make sure that cut-out portion of main frame is correctly placed on the square protrusion of Housing, Lower.

Front frame
Control of vertical level
[Reason]There is a possibility that printing failure occurs by front frame deformation.
[Service treatment]Handle Front frame in assembling/disassembling carefully.
IC holder
Handling of IC holder
[Reason]If IC holder is damaged in assembling/disassembling of your repair, there is a possibility that vital problem occurs in user’s further operation.
[Service treatment]Released two hooks of IC holder from the inside of IC holder by the tweezer.
[How to ensure of quality on re-assembled product]We judge that the quality of re-assembled product is ensured if there is no problem about the print result by adjustment program.

is adjustment is to optimize the timing belt tension for preventing tooth skip between pinion of CR motor and the CR timing belt. This adjustment must be made when CR timing belt is removed.
djustment Procedure]
Install the CR timing belt to the printer mechanism.
Check the CR timing belt tension by using Digital Tension Gauge.[Note] Before this adjustment, the following data should be inputted into Digital Tension Gauge.
[UNITTA : Setting of Digital Tension Gauge] - Weight : Input “0.4” - Width : Input “8” - Span : Input “377”
Return to CR unit to have position.
Set the sensor cable to the center of the timing belt vertically.(This time, the distance between the surface of the sensor cable on the timing belt is 10 ± 5mm.)
Push the upside of the timing belt with the tail plastic of ballpoint pen / plastic tweezers and check the timing belt tension on display of Digital Tension Gauge.
Check the result of tension value on the display.

.
Exterior partsUse a clean soft cloth moistened with water, and wipe off any dirt. If the exterior parts are stained by the ink, use a cloth moistened with neutral detergent to wipe it off.
Inside the printerUse a vacuum cleaner to remove any paper dust.
LD RollerWhen paper loading function does not operate because friction of the LD roller is lowered by any paper dust, set the adhesive side up of the cleaning sheet (included in the media) to remove any paper dust. Repeat loading the cleaning sheet several times.

Never use chemical solvents, such as thinner, benzine, and acetone to clean the exterior parts of the printer like the Housing. These chemicals may deform or deteriorate the components of the printer.Be careful not to damage any components when you clean inside the printer.Do not scratch the coated surface of the PF roller. Use soft brush to wipe off any dusts. Use a soft cloth moistened with alcohol to remove the ink stain.Do not use cleaning sheet included in the media for normal usage. It may damage the coated surface of PF roller.If the adhesive surface of the cleaning sheet is set to the LD roller shaft side and used to clean the LD roller surface, it is no problem. When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.
