4. Cleaning Your Machine This section describes the necessary cleaning procedures for your machine. 4-1 CAUTION • Be sure to turn OFF the power and disconnect the power cord before cleaning the machine. • If you turn OFF the machine, all the documents stored in memory are deleted. Print all the necessary documents stored in memory before turning OFF the machine.
Page 109: Cleaning The Interior
4-4. Cleaning The Interior Regularly clean the interior of the machine to avoid deterioration in print quality due to parts being dirtied by ink or paper dust. Figure 1-56 Cleaning The Interior 4-5. Cleaning the Feeder cover With a soft, clean, lint-free and dry cloth, wipe off any paper dust from the inside of the Feeder Cover as illustrated by gray colored part.

4-8 Cleaning The Bottom Plate Follow this procedure: 1. Connect the power cord, and power on the machine 2. Remove any paper from the Auto Sheet Feeder. 3. Prepare a sheet of A4 or Letter size pl a in paper. Fold it in half along the long edge. Unfold the paper, then load it in the paper support with the outside edge of the fold facing down.
Page 112: Transportation
5. TRANSPORTATION This section describes the procedures for transporting the printer for returning after repair, etc. (1) Keep the print head and ink tanks installed in the carriage. [See NOT E (1) on the next page.] (2) Turn off the printer to securely lock the carriage in the home position. (When the printer is turned off, the carriage is automatically locked in place.) [See NOTE (2) on the next page.] (3) To further secure the carriage to prevent movement from the home position during transportation, make and use a fixing tool in the following procedures:...
Page 113 Caution: (1) If the print head is removed from the printer and left alone by itself, ink (especially the pigment black ink) is likely to dry. For this reason, keep the print head installed in the printer even during transportation. (2) Securely lock the carriage in the home position, to prevent the carriage from moving and applying stress to the carriage flexible cable, or causing ink leakage, during transportation.

Page 115: New Technologies
1. NEW TECHNOLOGIES (1) Dye black ink adoption In addition to the pigment black ink, dye black ink is adopted in this machine, so that special paper can be printed in black ink. (For printing plain paper, the pigment black ink is used.) (2) Automatic Print Head Position Alignment In this machine, the print head position can be aligned automatically by operating the buttons on the operation panel and operating from the driver utility.
Page 116 Phenomena of predictable troubles and the Solutions (how to avoid the troubles)> < 1) Although the paper size is correct (A4/LTR) and the print head position alignment pattern is printed correctly, an error of the automatic print head position alignment failure occurs.
Page 117: Cleaning Mode And Amount Of Ink Purged
2. CLEANING MODE AND AMOUNT OF INK PURGED To prevent printing problems due to bubbles, dust, or ink clogging, print head cleaning is performed before the start of printing, except in the following cases: - Cleaning on arrival: Performed when the access cover is closed. - Cleaning by dot count: Performed after ejection of paper (or after printing on the back side of paper when auto duplex printing is performed).
