Introduction

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer-

ence to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates the

direction of the electric signal.

The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in

supplying the machine with power.

2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how-

ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.

In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors

used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the

DC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com-

municated in the form of Service Information bulletins.

All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be

able to identify and isolate faults in the machine."

1.2 Features

1.2.1 Features

0023-1255

iPF755

- High resolutions of 2,400 x 1,200 dpi maximum, coupled with the exceptionally light-fast, water-proof and ozone-proof five-color pigment inks of Y, M, C, PBK

and MBK, deliver high-quality photographic picture quality.

- Black ink suitable for the selected media type is automatically selected from two types of black ink, "black ink" for vivid and glossy printing and "matte black

ink" for matte and high-quality printing.

- A 160-by-128-dot-large LCD

- One-inch wide printhead having 2,560 nozzles per color, which are as many as the those of the existing models. High-density printhead technology "FINE" that

can satisfy both of beautiful and fast printing requirements of a high order is employed for accurate ejection of ultrasmall 4-pl drops of ink to the target positions.

Prints with 2,400 x 1,200 dpi resolution can be made at a high speed.

- Imaging processor "L-COA" incorporated for high-speed image data processing. High-speed processing of 5-color, 12-bit large-size images and printer control

for high-accuracy operation of high-density head can be performed with a single chip.

- Standard support for 10Base-T/100Base-TX/1000Base-T and USB 2.0 Hi-Speed.

- Borderless printing on and auto cutting of roll media.

- Hard disk drive mounted for greater ease of job management.

Functional enhancements new to this model include:

- All operations such as loading the roll media and cassette paper can be carried out at the front (top) of the printer, enhancing operability.

- The printer can be installed with its back in touch with the wall, requiring no installation space at the back of the printer.

- A subtank mounted at the ink port allows you to replace the ink tank during printing.

- The pressure of suction from the borderless printing ink catch groove changes automatically with the media size, preventing shift of media edges and staining of

the backside of the media.

- A printhead having nozzles (I-shaped nozzle) with a new shape reduces ink mist, ensuring superfine printing.

- Compatibility with e-maintenance/imageWARE Remote allows centralized management of customers' printer information.

- The newly designed operation panel allows you to operate the printer intuitively.

1.2.3 Printhead

0013-2741

iPF750 / iPF755

The printhead that mounts on the carriage is an integrated six-color disposable printhead.

It has 5,120 nozzles for MBK and 2,560 nozzles for each additional color arranged in a zigzag pattern.

If print quality remains unimproved even after a specified cleaning operation, replace the printhead. Replacement about one year after the date of initial unpacking

is also recommended.

1.2.4 Ink Tank

0012-6188

iPF750 / iPF755

Chapter 1

The ink tank is disposable.

There are four dye-based ink colors (black, cyan, magenta, and yellow) and one pigment-based ink color (matte black).

This printer features a mechanism by which only the correct color ink tank will fit in the given slot.

When the message No Ink is displayed, replace the ink tank with a new one. Also, each ink tank should generally be replaced six months after you have opened the

package.

0023-1308

iPF750 / iPF755

The roller holder accepts paper tubes having inside diameters of both 2 and 3 inches. It is furnished with attachments for 2- and 3-inch diameter paper tubes.

The roll holder clamps the paper tube of a roll not exceeding 150 mm in outside diameter from the inside.
