5.4.1 Data in the image storage memory (DRAM)

DRAM stores image data which was read other than by a direct transmission. It also acts as a buffer memory to store the image data received. If power is turned off, the memory clear list is printed automatically the next time the power is turned on. The user is thereby notified of the images that were erased from memory.

NOTE

Reception image data

This product is not equipped with image data backup, so that if the power

supply is cut, data in memory reception will be lost.

product does not have a memory reception image transfer capability. If

printing is disabled due to a fault in the printing section, check the Memory

If the setting is for the received image data to be transferred to PC, instead of being printed, the data will be saved as a file in the DRAM, and

5.4.2 Data in the control processing memory

SRAM is backed up by a lithium battery. It can retain the stored data for 5 years after the

power is turned off. SRAM stores the following data: All the data the user entered with the menu system, the activity reports and other report-generating data, the redial data containing the redial destinations set with the Redial key, the servicing data set by repair personnel with the service soft switch, and the CS LED lights-on duration data. SRAM stores almost all of the data which can be entered or set. These stored data can be checked with various reports.

Lithium battery life

The lithium battery can last for over 5 years after the power is turned off. When the power is on, the lithium battery’s power is untapped. Therefore, the actual battery life can be much longer.

When the lithium battery becomes exhausted, “DATA ERROR” will be displayed after the power is turned off or on. When this happens, replace the lithium battery. Since the data in SRAM will be lost when the battery is replaced, it cannot be printed out.

After the lithium battery is replaced and the power is turned on, “DATA

ERROR” will be displayed. Press the START/COPY key to discard the

contents in SRAM and initialize it to the factory defaults. Refer to Chapter 3: 3.7 CS LED reset the CS LED lights-on duration.

When the absorption amount of the waste ink absorber reaches 100 percent, the waste ink full error is generated and the printing operation is stopped to prevent the waste ink from The vertical alignment data is for correcting any vertical misalignment during bidirectional printing.

Initializing the upper document feed roller

When the separation roller starts to rotate, the position of the upper document

feed roller is simultaneously initialized to raise the document stopper Initialization is carried out when the power is turned ON, when documents are inserted and when documents are ejected.

Document feed lever

Switching between automatic document feed and manual document feed is carried out by the document feed lever above the left side of the LCD. During

automatic document feed, documents arc gripped between the separation guide and the separation roller. Switching the lever to manual document feed raises the separation guide and frees it from the document. Manual document feed can therefore minimize the possibility of damage caused by pinching between the separation guide and separation roller when feeding documents such as

thick-stock paper or photographs. However, because document separation does

not occur in manual document feed mode, only one sheet at a time

loaded. Loading multiple sheets will result in double feed.

Document feed error detection

There are three types of document feed errors which may occur.

a) Feed

b) Document extraction error

error

When the leading edge of the document is not detected by the document edge sensor (DES) within 15 seconds after the start of document feed, a feed jam error is detected and document feed is terminated.

NOTE

This model has no paper selection lever on the automatic sheet feeder.

If the paper meets specifications, it can be fed without selecting operation the paper type.

The paper is loaded in the auto sheet feeder such that a corner of it is caught by

the paper separator. When printing starts, the pick-up roller starts to rotate

through the drive of the paper feed motor. Plain paper is fed with its corner held by the paper separator, and then pushed into the paper feed section. When printing on thick paper like envelopes, as the paper is stiffer than the return force of the paper separator’s spring, the paper separator is pressed

down to feed the paper.

Initial position of the pick-up roller is detected when the flag is sensed by the

pick-up roller sensor on the PCNT board.

When the paper is sensed by the paper edge sensor for over a second, it is fed

automatically until it reaches the starting position for printing.

If the paper is not sensed even when the paper pick-up operation is executed, it

is executed again. If the paper is still not sensed, it is assessed as a paper feed

error.

When manual feeding, set the paper in the manual feeding slot until it reaches

the position where the paper edge sensor detects the paper.

Paper pushed into the paper feed section is fed to the starting position for

printing after it has been sensed by

At this time, the paper passes through a different paper path from that of the

4. Carriage

Driven by the carriage motor, the carriage moves horizontally across the paper. Through the carriage ribbon cable, the printing signals from the logic board are transmitted to the

cartridge in the carriage.

By controlling the purge unit’s slide lock pin, the carriage controls the engagement of the paper feed motor’s drive power between the paper feed/purge unit and the sheet feeder.

5. Paper thickness adjustment lever

Adjust the gap between the print head and paper according to the thickness of the paper.

6. Purge

In order to maintain the BJ cartridge’s high print quality, the BJ cartridge’s nozzles and spray orifices are cleaned by a wiper and pump. When in standby mode, the BJ cartridge’s spray orifice section is covered by a rubber cap to prevent the nozzles from drying out and ink from leaking. The purge unit controls the swing gear. This gear switches power from for separation of the paper, paper feed and nozzle cleaning.

NOTE

Print Shift Correction

Print gaps cm occur when doing bidirectional printing, due to changes in the weight of the BJ cartridge and mechanical errors. This gap is corrected adjusting the carriage drive motor load and the carriage position, which determined logically from the number of stepping pulses. Gap detection performed before the start of printing, during the home position detection operation.

NOTE

Ink empty detection

Ink empty detection during fax operation is performed by firing black ink between the light source and of the printer. This function does BC-20. When ink passes between the source and the receptor, as shown in Figure the sensor output will be a pulse waveform. The presence of ink may be determined from the pulse generation time. Ink empty detection is performed at the end of each received page of printing. If ink is not detected on the first detection attempt, the ink nozzle is shifted slightly, and the detection operation is repeated to double-check the first detection operation. If it is determined that there is ink remaining, the image data for that page will be erased from memory. If the cartridge is out of ink, the message cartridge is out of ink, and the page will be “received” to memory again from the image data. The detection level of the ink detection sensor is adjusted automatically by means of a feedback circuit, and thus requires no manual adjustment. If the sensor output does not reach a standard control (such as if occurs), the ink sensor failure will be reported with the display of the
