PAGE 43
4) ROM SPACE 1) BLOCK DIAGRAM Fig.5 shows the ROM space. The UP-700 uses 2MB of NOR-type flash memory instead of conventional ROM, so that the FROS1# from the MPCA9 is input into the chip enable of the flash memory. Here is the block diagram of the LCD and its allied components. 200000h * Lower 64KB of the ROS1 is mapped on the 0 page area.

CHAPTER 3. HANDLING THE PRINTER 1 Special Handling Considerations (1) When transporting the printer • When transporting the printer, the head up lever should be raised in the : Head up position so that the head does not contact the platen rollers. Failure to do so may result in poor the printer performance. :Head-up position The head is not in contact with the platen roller. To be used when the printer is out of service for a long time or when it is to be transported.
PAGE 90
(2) When storing the printer 2. Loading the Paper (insertion and removal) Printer • When storing the printer, make sure to raise the head up lever in the : Head up position. Never store it with the position or : Cleaning position. : Close • Avoid storing the printer in areas with a lot of dust, direct sunlight, or high humidity. • If the printer is stored for an extended period, put it in a antistatic bag and store it in a dry place.
PAGE 91
(2) Unloading the paper 2. Inspection The paper can be unloaded in two ways. Move the head up lever toward : Head up position and then pull the paper out by hand in the forward direction (feeding direction) or in the reverse direction. Operate the paper feed keys to discharge the paper from the printer. Move the head up lever to the head up position and remove the paper toward the front.
PAGE 92
(2) Periodic checks Check the items listed in the table below every 6 months, and correct any problems. Table of periodic checks No. 1 Check items Standard Procedure Dust, lint and dirt • The mechanism should not have a lot of dirt, lint or dust on its surface. sticking to various Foreign substances should not be allowed to collect. parts. • The paper guide should not be clogged with paper chips, etc. • See "Chapter 6". 2 Lubrication 3 Operational check • Printing occurs without abnormality.

The printing color is light. Dots are missing occasionally or the color of some dots becomes light. The overall printing color is light. Cause Level Checkpoints and Checking Method Repair Method (1) The Head cable is disconnected. A • Verify that the Head cable is properly connected.
PAGE 94
Phenomenon 5. Paper cannot be loaded. 6. Paper is not fed. 7. The paper feed pitch is not uniform. Condition The end of the roll paper cannot be inserted into the paper guide section. Roll paper is not fed, and printing is repeated on the same line. The line spacing is not uniform. Cause Level Checkpoints and Checking Method Repair Method (1) The leading edge of paper roll is improperly cut . A • Check that the leading edge of the paper roll is properly cut and is not folded.
PAGE 95
Phenomenon Condition Cause Because the tension to take up the roll paper is weak, the diameter of the paper taken up becomes larger. Checkpoints and Checking Method Repair Method B • Verify that the paper take up shaft is not worn or damaged. • If any wear or damage is found, replace the paper take up shaft. (2) SP gear, C-spring or pulley is worn or doesn’t rotate smoothly. B • Check paper winding parts for wear and damage. • If wear or damage is found, replace the part with a new one.

CHAPTER 6 DISASSEMBLY AND ASSEMBLY • This chapter describes the procedure for disassembling the printer. It is advisable to reinstall the printer in the reverse order from disassembly, referring to "Cautions to be taken when installing." • Some easy steps have been omitted. • Only part names are described without indicating their part codes.
