1-4-1 Error codes

(1) Error code

Error codes are listed on the communication reports, activity report, etc. The codes consist of an error code indication "U" followed by a 5-digit number. (Error codes for V34 communication errors start with an "E" indication, followed by five digits.) The upper three of the five digits indicate general classification of the error and its cause, while the lower two indicate the detailed classification. Items for which detailed classification is not necessary have "00" as the last two digits.

1-6-1 Updating the firmware

(1) Updating the firmware on the fax control PCB (FLASH ROM)

Perform the steps below when updating the firmware in the Flash ROM on the fax control PCB. Firmware updating requires the following tools:

Flash tool assembly (P/N 3596801*) Control ROM IC1 (P/N 3CM6802*) Control ROM IC2 (P/N 3CM6806*)

Caution:

• Turn the main switch off and disconnect the power plug from the wall outlet before disconnecting or inserting connectors.

1. Turn the main switch off and disconnect the power

plug from the wall outlet.

2. Remove the two screws holding the rear cover and

then the cover.

3. Remove the five screws holding the fax shield cover

and then the cover.

4. Fit control ROM IC1 and control ROM IC2 to the

flash tool assembly.

(2) Updating the firmware on the fax control PCB (Compact Flash card)

To carry out a FLASH ROM firmware update of the fax control PCB, follow the steps below. This firmware update requires the following tools:

CF jig (P/N 3CM6803*) Compact Flash card (Products manufactured by SANDISK are recommended.)

Caution:

• Turn the main power switch off and disconnect the power plug from the wall outlet before disconnecting or inserting connectors.

• When writing data to Compact Flash card from a computer, be sure to format it in advance. (For formatting, insert a Compact Flash card and select a drive.)

• For a desktop computer, connect a Compact Flash card reader/writer to it. For a notebook computer, use a PC card adapter or a connection portion only for Compact Flash card.

1. Check the current ROM version using maintenance mode U680.

2. Turn the main switch off and disconnect the power plug from the wall outlet.

3. Remove the rear cover and the control-box cover. (Refer to“(1) Updating the firmware on the fax control PCB (Flash

ROM)”, Steps 1 to 3, above.)

4. If you are using a new CF jig, continue as follows to write the boot program into the jig's flash boot. If your CF jig

already has the boot program in its flash boot, jump ahead to step 13.

5. Insert a Compact Flash card containing the boot

program into the CF jig. Be sure that the card fits in smoothly along the left and right guides. (Trying to force the card in incorrectly may cause electrical contacts to break.)

Figure 2-2-1 Fax control PCB block diagram

The fax control PCB (FCPCB) controls the overall fax operation. To transmit a fax, image data scanned by the optical section of the copier is processed by the main PCB (MPCB) and then sent to the fax control PCB (FCPCB). Received image data is first stored in the bitmap area of the SDRAM IC21 page by page and compressed using the MH, MR or MMR method. The data is then stored in the image memory area of the SDRAM IC21 and sent to the modem LSI IC81 to be modulated from digital signal to analog signal before it is sent to the telephone line via the NCU PCB (NCUPCB). T o receiv e a f ax, analog image data received from the telephone line via the NCU PCB (NCUPCB) is sent to the modem LSI IC81 and, after demodulation into digital signals, stored in the image memory area of the SDRAM IC21. The image data is then decompressed and converted into the bitmap area of the SDRAM IC21 page by page and sent to the ASIC IC71 for resolution conversion and smoothing, and is passed to the main PCB (MPCB) as print image data.

3CM The NCU PCB (NCUPCB) mainly controls the connection to the telephone line. It consists of the circuits sho wn in the bloc k

diagram. The loop current detection/tone signal reception circuit IC30 detects the DC loop current formed at the DC loop/dial pulse transmission circuit PC80 to determine the status of the telephone line. It also receiv es tone (DTMF) signals during remote control. The ring signal detection circuit PC60 detects the ring signals from the telephone line to determine call reception. The DC loop/dial pulse transmission circuit PC80 turns on and off the DC loop formed in the telephone line to send out dial pulses (selection signals). The e xternal telephone off-hook detection circuit (T40 and PC40) detects the off-hook state of the

telephone connected or the handset*

. The destination identification circuit (JP20, JP21 and JP22) is used b y the fax control PCB (FCPCB) to identify the destination of the NCU PCB (NCUPCB). The accounting pulse elimination circuit L70 removes signals representing the communication charge information (accounting pulses) before they reach the modem when

telephone line is used.* requests an outside connection to the private branch exchange (PBX) when calling via the PBX.*

This is because accounting pulses obstruct fax communications. The ground start circuit PC10

Figure 2-2-4 Auxiliary power source PCB block diagram

The auxiliary power source PCB (APSPCB) is a switching regulator that conv erts an AC input to generate 5.2 V DC and 12 V DC. It consists of a switching control circuit, 5.2 V DC output circuit and 12 V DC output circuit. The rectifier circuit rectifies the full-wave of the AC input using the diode bridge D2. The smoothing capacitor C7 smoothes out the pulsed current from the diode bridge. The switching control circuit turns on/off the power MOSFET Q2 with the voltage induced in the controlling coil of the transformer T1 to switch the current induced in the primary coil of the transformer T1. The 5.2 V DC output circuit smoothes out the v oltage from the current induced in the secondary coil of the transformer T1 via the diode D5 and smoothing capacitors C15 and C91, and outputs a stable 5.2 V DC using the shunt regulator IC1. The output status of the 5.2 V DC is f ed bac k to the switching control circuit via the photo-coupler PC1. Based on the feedback, the switching control circuit changes the duty cycle of the pulse that turns power MOSFET Q2 on/off in order to adjust the

5.2 V DC. The 12 V DC output circuit smoothes out v oltage from the current induced in the secondary coil of the transformer T1 via the diode D6 and smoothing capacitor C19, and generates a stable 12 V DC using the 3-pin regulator IC2. The relay turns on/off the AC supply to the power source PCB (PSPCB) based on the remote signal from the fax control PCB (FCPCB).
