Find the part(s) you removed or replaced, and check which adjustment(s) must be carried out.Note: “O” indicates that the adjustment must be carried out. “O *” indicates that the adjustment is recommended. “---” indicates that the adjustment is not required. If you have removed or replaced multiple parts, make sure to check the required adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry out them in the order given in the “Priority” row. „When the EEPROM Data Copy cannot be made for the Main Board that needs to be replaced, the Waste Ink Tray Assy must be replaced after replacing the Main Board with a new one. „After all required adjustments are completed, use the “Final check pattern print” function to print all adjustment patterns for final check. If you find a problem with the printout patterns, carry out the adjustment again. „When using a new Main Board for replacing the Printer Mechanism, the Initial setting must have been made to the Main Board.

See “ 2.1 Required Adjustments (p34) ” for the adjustments not explained here. 2.2.1 TOP Margin Adjustment Three adjustment patterns are printed on the top of the paper as shown in Figure 2-1. Figure 2-1. Top Margin Adjustment Printout Pattern How to Judge Check if the top edge of the paper is within -3 to +3 steps from the standard line. Additional Information If it is not within the OK range, select the adjustment value (-4 to +4 steps) on the adjustment program to adjust the top edge of paper until it becomes within -3 to +3 steps from the standard line. Then, print the adjustment pattern again to check the result. „The patterns are printed on three sections. If those three patterns are in different position to the top edge of paper, the paper was fed on a skew. Set the papers correctly and print it again to adjust the top margin correctly. „The following pattern is printed with the optimal adjustment value.

Confidential Maintenance Overview 38 L200/L201/L100/L101Revision A 3.1 Overview This section provides information to maintain the printer in its optimum condition. 3.1.1 Cleaning Except for the printhead, there are no other mechanism parts or units that require periodic cleaning. However, if need arises, clean the component observing the following instructions. †Instructions for cleaning „ Exterior parts such as housing Wipe dirt off with a soft clean cloth moistened with water. For glossy or transparent parts, use of unwoven cloth is recommended to avoid scratching those parts. „Inside of the printer Remove paper dust with a vacuum cleaner. „Rubber or plastic rollers such as an LD roller used to feed paper If paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol. †Instructions for cleaning ink stains Wipe the stains off with a cloth wrung out of diluted alcohol. 3.1.2 Lubrication The type and amount of the grease used to lubricate the printer parts are determined based on the results of the internal evaluations. Therefore, refer to “ 3.2 Lubrication Points and Instructions (p39) ” for the repairing procedures below, and apply the specified type and amount of the grease to the specified part of the printer mechanism. Before applying the grease, make sure to wipe off old grease completely with BEMCOT. †Grease †Tools „Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get cloudy. „When wiping paper dust off the LD roller, be careful not to rub against the surface asperity. „To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether. „After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free cloth to remove alcohol traces fully.
