1.5.2 Power On Default Settings
The printer also lets you change some of its power on parameters. To change the settings shown in Table 119, Group 3 Features (Power on settings), follow the steps below. 1. Turn on the printer while pressing the PAUSE, PAPER FEED, and FONT buttons. 2. Press the button indicated in Table 1-19 for a few seconds to change parameters. Table 1-19. Group 3 Features (Power-on Settings) Button [PAUSE] [PAPER FEEDI [FONT] Feature Input buffer Draft printing speed Auto CR Setting valid (**) or invalid (*) high (**) or normal (*) valid (**) or invalid (*) standard setting Notes: 1) Auto CR moves the next print position to the left margin when LF or ESC J code is sent. 2) `*' is one beep, and `**' is two beeps. If no operation is executed within a few seconds, the printer exits the power on selection mode with five beeps (*****). The selected value is stored in non-volatile memory. * The printer automatically becomes ready to print after the selection.
1.5.3 Buffer-full Printing 1.5.4 Hexadecimal Dump
Press the PAUSE button while turning on the printer to put the printer in hexadecimal dump mode. In this mode, received data is printed out in hexadecimal format, along with the corresponding ASCII characters. This function is useful to check received data from the host. If a received code is not a printable ASCll character, the printer prints a period (.) in the ASCII column.

REV.-A 1.5.5 Self Test Press the PAPER FEED button while turning on the printer to put the printer in self-test mode. To stop the self test, turn off the printer. (The control panel is still operational in self-test mode for paper handling and font selection. ) When pages are printed from the CSF, the first sheet is used for scaling the sheet length. Then, the maximum number of printable lines is printed in the bottom line of the sheet and saved in non-volatile memory as the default page length. Page lengths are saved individually when a dual bin CSF is in use. The self test prints out the following: (a) Maximum printable lines (only on cut sheets from the CSF) (b) Firmware version (c) Current default settings (d) Short help messages for control panel operation (e) A Pattern of characters, as shown below.
Figure 1-9. Self Test Printout
1.5.6 Paper-out Detection
When the paper-out sensor detects a paper out, the printer enters the pause condition automatically after feeding or printing several lines. When a paper-out is detected, load new paper properly and set the printer ready to print by pressing the PAUSE button. 1.5.7 Auto
Tear-off
a., {.>, , ..-""
When the release lever is set to one of the tractor positions, the paper advances to the tear-off position automatically if the input data buffer is empty and the paper is at the top-of-form position (If the printer receives no additional data after it has received a form feed). If subsequent data is sent to the printer, the paper reverse feeds to the original position automatically and the printing starts. This function can be turned off in the default setting mode. 1.5.8 Thermal Protection
When the printhead temperature exceeds 82 deg. C, the printer stops printing to protect the printer from overheating. 1.5.9 High Duty Printing
The printer stops printing when the printing duty is too heavy for the printer's power supply. If it occurs, the :" . printer continues printing the rest at half speed. 1-24
REV.-A , 1.5.10 Sheet Loading and Sheet Ejection The release lever engages or disengages the push-tractor unit drive mechanism. The lever's operation provides with improved paper-handling functions: (a) Automatic cut sheet loading without the cut sheet feeder Move the release Ievertothe FRICTION position and load a sheet using the paper guide (top or optional front). A few seconds later, the sheet is automatically loaded to the top-of-form position, and the printer becomes ready to print. (b) Automatic cut sheet loading and ejection with the cut sheet feeder Move the release lever to the FRICTION position and load a stack of paper into the hopper of the cut sheet feeder. Pressing the PAPER FEED button loads the sheet to the top-of-form position. If a paper-out is detected before printing starts, the sheet is automatically loaded to the top-of-form position, without the PAPER FEED button being pressed. (c) Continuous paper loading and ejection (paper park) Move the release lever to REAR PUSH/FRONT PUSH position and load the paper into the tractor unit. Press the PAPER FEED button to load the paper automatically to the top-of-form position. If a paper-out is detected before printing starts, the paper is automatically loaded to the top-of-form position, without the PAPER FEED button being pressed. If the FONT+ PAPER FEED buttons are pressed when the continuous paper is loaded, the paper is ejected backward to the paper park position. To feed several pages backward, repeat this operation several times.
1.5.11 Adjust Lever Operation
The platen gap adjust lever must be set to the proper position (from the 8 step available) for the paper thickness.lf this lever is set to the position 2 (4th step) or higher, printing speed and paper feeding speed will be reduced. Table 1-20. Lever Positions Lever position O (2nd step) 1 (3rd step) Paper thickness 0.06-0.12 mm 0.13-0.17 mm I 0.18-0.25 mm 0.26-0.32 mm

2.1 Printer Mechanism Operation
This section describes the printer mechanism of the FX-870/l 170 printer and explains how the printer works. The FX-870/l 170 printer mechanism features a 9-pin impact dot printhead for seriaI Printin9. It has four main parts: 1) the printhead mechanism, 2) the carriage movement mechanism, 3) the paper feed mechanism, and 4) the ribbon advance mechanism. Each of these is described below.
2.1.1 Printhead Mechanism
The printhead mechanism consists of the printhead itself, the ink ribbon, and the platen. The printhead contains a column of 9 wires. Each of these wires has a drive coil which causes the wire to move in and out of the printhead to print each dot. The four steps below describe how these driving wires work. (1) The control circuit outputs drive signals to the printhead drive circuit. This changes the printhead drive voltage, and current flows through the corresponding printhead coil. The coil acts as a solenoid and generates a magnetic force. (2) Thisinducedforce causesthe plate toapproach the coil rod andtheassociated dotwire is rapidly ejected to impact on the platen. (3) The dot wire presses the ink ribbon up against the paper as it hits the platen and in this way prints a dot on the paper. (4 As soon as the current through the coil is switched off, the force induced in the coil rod stops. The plate then returns to its original position (the position assumed before the coil was energized) through the action of the plate spring. After the dot wire hits the platen, the rebounding force of hitting the platen works with the wire resetting spring to pull the wire back to its original position.

. REV.-A Figure 2-1 shows the action of the printer mechanism when a single dot is printed.

Figure 2-1. How the Printhead Works
The printhead tends to heat up after a period of continuous printing. To minimize the dot wire drive coil overheating, the head is equipped with a thermistor that can detect the head temperature. When the thermistor detects changes in the printhead temperature, the voltage signal changes. The CPU detects the voltage change and stops printing until the head temperature cools. The printhead is also used asa buzzer. Head driving coils move allthedotwires backandforth atafrequency -.,, of 1.5 KHZ for 40 I.M without impacting the platen, so that the wires vibrate. The vibrating dot wires sound like .=: { a buzzer.

` 2.1.2 Carriage Mechanism
The timing belt is connected to the lower side of the carriage. With the printhead installed, the carriage moves in either direction along the carriage guide shaft. The carriage (CR)motor (a stepping motor) drives the timin9 belt which moves the carriage. The home position (HP) sensor detects the home position of the carriage. NOTE: Carriage initialization for the 80-coIumn and 136-column models are different.

2.1.3 Platen Gap Adjustment
of differentweights orthicknesses. When the platen gap adjust lever is moved forward or backward, the carriage guide shaft rotates. This rotation moves the carriage either toward or away from the platen and changes the platen gap. Setting the adjust lever to position 2 (the 5th slot from the top) turns off the platen gap switch, which slows down the printing speed of the printerto protect the printhead. The PG detector detects the position of the adjust lever. The correct platen gap is 0.38mm * 0.02mm with the adjust lever set to position O.

2.1.4 Paper Handling Mechanisms
During normal operation, the paper is fed to the printer, advanced to the specified position, and ejected from the printer. These paper handling operations are performed by various paper handling mechanisms, such as the tractors, platens, rollers, and gears. T
