the auto cutter unit. WARNINGS (1) Before starting installing, removing or repairing, be sure to turn off the power of the printer and disconnect the power cord from the power source. (2) During disassembly/reassembly or adjustment, do not touch the cutting blade as it is very dangerous. (3) Do not insert a foreign object such as a paper clip into the cutting blade section. (4) When cleaning the cutter blade, use a cotton swab that is soaked in ethyl alcohol. Do not directly wipe with a soft cloth as the cutting blade is very dangerous. CAUTIONS (1) Do not disassemble/reassemble or adjust the auto cutter unit, if it functions properly. Particularly, do not loosen screws on any component, unless necessary. (2) After completing an inspection and before turning on the power, be sure to check that there is no abnormality. (3) Do not put anything on the covers, etc. during maintenance or while the printer is in operation. (4) During maintenance, be careful not to leave parts or screws unattached or loose inside the auto cutter unit. (5) When disassembling or reassembling, check cables for any damage and make sure that they are not caught by covers, etc. CLP-521, CLP-621 & CLP-631 ii

However, the procedure for CLP-621 and CLP-631 is basically the same as for CLP-521. - The auto cutter unit cannot be installed on the printer if an optional peeler unit is attached. Therefore, remove the peeler unit before installing the auto cutter unit. 2-3-1. Installing the Cutter Stand Unit 1. Turn the printer off and unplug the power cord from the printer. 2. Open the Top Cover SA. 3. Lift the Front Cover upward and remove it from the printer. Note: Keep the Front Cover as it will be used again when the auto cuter unit is removed from the printer.

CLP-521, CLP-621 & CLP-631 2-4 4. Remove the one screw (PH, M3x3) that fastens the Motor Cover, and detach the Motor Cover. In this case, pay attention not to drop the screw inside the printer. Note: Do not touch the motor as it can get hot. 5. Remove the one screw (PHT(BH2T), M3x14) that fastens the Connector Cover, and detach the Connector Cover. 6. Connect the cable of Cutter Stand Unit to the connector (CN15) on the Main PCB Unit of the printer. In CLP-621 and CLP-631, the screw is fastened in the horizontal direction.

2-5 CLP-521, CLP-621 & CLP-631 7. Run the cable stated in step 6 along the printer case as shown below. In this case, run the cable so that it will not be caught by the Connector Cover or Motor Cover that will be installed again. 8. Fasten the Cutter Stand Unit to the printer with the attached two screws. Cable

CLP-521, CLP-621 & CLP-631 2-6 2-3-2. Installing the Cutter Unit After attaching the Cutter Stand Unit to the printer, install the Cutter Unit as follows: 1. Connect the cable of the Cutter Unit to the connector of the Cutter Stand Unit (X). 2. While aligning two convexes at the bottom of the Cutter Unit with two projections of the Cutter Stand Unit (Y), fasten the screw knob of the Cutter Unit with a flat-bladed screwdriver to install the Cutter Unit to the Cutter Stand Unit (Z). In this case, pay attention so as not to pinch the cable with the Cutter Unit. 3. Install the Motor Cover and Connector Cover on the printer body. 4. Close the Top Cover SA. 5. Connect the power cord and turn on the power switch of the printer. 6. Perform self print function and check for correct cutter operation. Refer to "3.2 Cutter Operation Check" in Chapter 3 "Adjustments".

2-7 CLP-521, CLP-621 & CLP-631 2-3-3. Removing the Auto Cutter Unit Note: Before starting work, be sure to turn off the power of the printer and disconnect the power cord from the power source. Remove the Auto Cutter Unit from the printer by performing reverse procedure to installation procedure. In this case, while detaching the Cutter Unit from the printer by removing the fastening screw, hold the Cutter Unit by hand as it can fall down. 2-3-4. Caution when replacing parts If the following part is removed from the Cutter Stand Unit, adjustment is required when assembling. 1 Static Eliminator Sheet Positioning is required. 2 Metal parts that regulate the cutter slit width Refer to Chapter 3 "Adjustments". Static Eliminator Sheet Sticking Position: Stick the Static Eliminator Sheet to the position shown below.

CLP-521, CLP-621 & CLP-631 3-2 3-1. Mechanical Adjustment When the following part is replaced, perform cutter slit width adjustment explained here. - Cutter Stand Plate - Cut Guide 2 Plate (Adjustment is also necessary when it is reassembled.) 3-1-1. Cutter slit width adjustment 1. Using thickness gauges (0.9 mm and 1.0 mm), check the cutter slit width in the Cutter Stand Unit. 1) Be sure that the 0.9 mm thickness gauge can pass through the slit on both right and left sides. 2) Be sure that the 1.0 mm thickness gauge cannot pass the slit on both sides. 2. If satisfactory results are not obtained, adjust the slit width as follows: 1) Loosen (not remove) the two screws "A" on the back of Cutter Stand Unit. 2) Adjust the slit width while sliding the Cut Guide 2 Plate located in the lower part of Cutter Stand Unit. (The Cut Guide 2 Plate moves vertically along the elongate holes "B".) 3) Be sure that the 0.9 mm thickness gauge passes through the slit but the 1.0 mm thickness gauge does not pass it through. Note: Perform this check on both sides of the slit to ensure the parallelism of the Cut Guide 2 Plate against the Cut Guide 1 Plate. 4) Tighten the screws "A" to fasten the Cut Guide 2 Plate.

3-3 CLP-521, CLP-621 & CLP-631 3-2. Cutter Operation Check After installing the auto cutter unit in the printer, perform the self test to check the cutter operation. Self print pattern is printed over two pages and each page is automatically cut. 3-2-1. Operation in self print mode Install the media and operate the printer as follows: Case of label media: Turn on printer power while pushing the FEED key. When the PRINT LED has begun to flash slowly, release the FEED key. After it enters TEST MODE and media has fed, two labels print then printing stops. To restart printing, press the FEED key once more. Case of continuous media: Turn on printer power while pushing the FEED key. When PRINT LED has stopped flashing slowly and has begun to flash rapidly, release the FEED key. After it enters TEST MODE, it prints and then printing stops. To restart printing, press the FEED key once more. Paper feed direction 1st sheet 2nd sheet Cut position Cut position Self test print pattern

CLP-521, CLP-621 & CLP-631 3-4 Notes: - With the original factory settings, the printer automatically recognizes installation of the Auto Cutter Unit. - If cutting operation is not performed, "Auto Configure" option in the "After Print" menu may be set to "Off". In this case, set it to "On" and then retry self test print operation. *: To change the menu setting, refer to the User's Manual. - Cutter operation is possible even when "Auto Configure" option in the "After Print" menu is set to "Off". To enable the cutter operation, select "Cut On" in "Function Select" of the "After Print" menu, and then perform self test print operation.
