Check the following particulars.† Execute head cleaning or initial ink charge. 1. Execute head cleaning or initial ink charge by one of the following methods. 2.Nozzle Check Pattern Printing (p.59) Execute Nozzle Check Pattern Printing in the Panel Setting menu. (Panel Setting → TEST PRINT → NOZZLE CHECK) † If the power cleaning does not recover the printer, check the following points.„ If trouble occurs in all the ink colors.•Are the Print Head and Cap Unit sealed during Ink Charge?•If the Cap Unit / Pump Tubes have come off.•If the life of the Cleaning Unit has expired.•If the Cap Unit has failed.

Perform the adjustment below with Adjustment Program. 1. Nozzle Bi-D Adjustment (p.393) 2. Auto Bi-d Adjustment (p.430) 3. Auto Uni-d Adjustment (p.401) 4. Check Platen Gap (p.410) Execute Nozzle Check (p.436) and Alignment Check (p.437) above adjustment. If print quality is still abnormal, go to next step. 2. If the trouble occurs only when the user is using a specific type of paper (thick paper), carry out User Paper Setting using the panel setting procedure. (By setting the information concerning the thickness of the paper the user is using and correcting the print position (correction of changes in the position where ink hits the paper surface due to differences in paper thickness), avoid influencing the print position.) 3. If this problem occurs after replacing the BOARD ASSY., MAIN with a new one: „ Transfer the parameters on the old Main Board to the new board. (p.409) 4. If the printers condition is not improved by the above items (adjustments), replace the following parts. „ Printhead (p.285) „ Printer Mechanism (SP) (p.242) SMUDGED OR MARRED PRINTOUT (FRONT SIDE) If smudging or marring occurs due to rubbing by the head, etc. on the papers printed surface, check the following items. 1. If smudging is occurring at the front end of the roll paper or at the rear end, widen the margins at the front end and rear end. (Set the PAPER MARGIN front end and rear end on 15mm.) (If high duty printing was done close to the front end and rear end (margin = 3mm), the paper will contain a large amount of ink and deformation of the paper will be accelerated, and depending on the case, the paper will touch the head.) 2. If paper with weak edges which cannot move smoothly along the paper path is being used, Select -4 for SUCTION in the CUSTOM PAPER, which is in the Panel Setting. 3. If there is rubbing and smudging due to slow drying in printing of user paper. In the item DRYING TIME in the CUSTOM PAPER, in Panel Setting set the drying time (the time until auto paper cutting is carried out after printing is finished. (Default: 0 second; Maximum: 10 seconds) 4. If the trouble cannot be resolved by the above methods, check the following. „ Pump Unit failure „ Check to see if dust containing ink, foreign matters or paper is adhering to the side surface of the head. 5. Extend platen gap. NOTE:Be careful to decreasing image quality, if the platen gap is extended.

Check if the paper is bent or curled, and replace the paper with new one if abnormal. 2. Check to see if there isnt ink adhering to the paper feed path. If there is ink adhering, it should be wiped off. „ PF Roller surface „ Front Eject Paper Guide surface „ Rear Paper Guide surface (including switching ribs) „ Paper Eject Roller surface 3. Check if ink absorbing sponge for borderless printing, and correct if it is abnormal. „ Deformation „ Embossment (installation failure) „ Accumulation of ink WHITE OR BLACK BANDING IN THE CARRIAGE RUNNING DIRECTION If white or black banding (uneven density) in parallel with the Carriage Unit running direction appears on your printout, check the following points: 1.Nozzle Check Pattern Printing (p.59) Execute Nozzle Check Pattern printing in the panel setting menu. If dot missing is found, perform the head cleaning or initial ink charge by following method „ Cleaning (p.412) of adjustment program. „ Power Cleaning (p.79) in Panel Setting Mode. „ Initial Ink Charge (p.412) of adjustment program. 2. Adjustment If dot missing is not found, perform the following adjustment and check for improvement. „ Check Alignment (p.437) If it has trouble, execute Power Cleaning (p.79) or Initial Ink Charge (p.412). „ 1000mm Feed Adjustment (p.407) If the users paper size setting is not correct when PPR SIZE CHK / PPR ALIGN CHK of panel setting menu has been set to OFF, then printing will be done onto platen surface.
