4. PRINTER TRANSPORTATION METHOD 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 Caution 1 below.) 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 Caution 2 below.) Confirm that the paper lifting plate of the sheet feeder unit is raised.(See Caution 3 below.) 3.
Part 2 TECHNICAL REFERENCE
1. NEW TECHNOLOGIES (1) CD-R feeding mechanism For the i9950 model, the paper output tray serves as the CD-R tray feeder. (For the i9900 model, the paper output tray serves only its original function, as the model does not support CD-R printing.) 1. How to set the paper output tray when performing CD-R printing. By pressing the CD-R tray lever down, the paper output tray is raised to the CD-R printing position from the paper printing position.
2. How to set the paper output tray when performing paper printing By lifting the front of the paper output tray up slowly, the paper output tray returns to the paper printing position from the CD-R printing position. Problem If the paper output tray is in the CD-R printing position, when the access cover is opened with the printer powered on, the carriage does not move to the center.
(2) Independent cleaning For i9900/i9950 models, the print head consists of two blocks (C, M, Y and PM, R, BK, G, PC). As a result, it is possible to select either a specific block, or both blocks, for cleaning. For the i9100 model, which has only one block, it was possible only to perform bulk cleaning. The example print head composition is for the i9900/i9950 model. The i9900/i9950 print head consists of two blocks with eight colors (PM, R, BK. G, PC and C, M, Y, from left to right).
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 - Manual cleaning / deep cleaning: Performed manually. Group 1 includes BK/R/G/PC/PM, and Group 2 includes C/M/Y.
