IMPORTANT SAFETY NOTICES

+
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. Note that some components of the printer are supplied with electrical voltage even if the main switch is turned off.
HEALTH SAFETY CONDITIONS
1. If you get ink in your eyes by accident, try to remove it with eye drops or flush with water as first aid. If unsuccessful, get medical attention.
2. If you ingest ink by accident, induce vomiting by sticking a finger down your throat or by giving soapy or strong salty water to drink.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The printer and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.
2. The RAM board has a lithium battery which can explode if handled incorrectly. Replace only with the same type of RAM board. Do not recharge or burn this battery. Used RAM boards must be handled in accordance with local regulations.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Dispose of replaced parts in accordance with local regulations.
2. Used ink and masters should be disposed of in an envionmentally safe manner and in accordance with local regulations.
3. When keeping used lithium batteries (from the main control boards) in order to dispose of them later, do not store more than 100 batteries (from the main control boards) per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

2. Paper Deli v er y Table
[B]
The C226 model use s a new paper delivery tabl e. This table has newly added small guide plates [A] on each front and rear side fenc e. The guide plates stack the prints more evenly. The small guide plat es [B] , on the bottom of each side fence keep the prints ali gned in the center of the table while the copies are stacked. Also, the paper stack ca pacity has been incre ased from 500 sheets to 1000 sheets.
[C]
Due to the the new paper del ivery table design, a new auxiliary bracket [C] has been added for optional TAPE MAKER installation. For details, refer to the "Tape Maker Installation" section.

The thermal hea d dr ive voltage has been decreased from 24 V to 16V because the sm all er heating element s in th e th er m al head require less power.
The power supply boar d has been modified to output 16V to drive the thermal head.
An ON/OFF switching circuit for the thermal head drive voltage (VHD) has been add ed t o th e power supply board.
The design of the fron t co ver and the model name pr i nt ed on the cover have been changed. This was done for marketing rea sons and to ensure that the us er s do not confuse the C211/ C 21 2/ C 213 models with the C207/C208 models and use the wrong mast er ty pe. (The new master is more sensitive.)
The C213 make-up control board has been eliminated because the C213 image pro ces si ng boar d performs the Mak e- up function.
A VHD ON/OFF line has been added to the main har ness.

The sheet through type ADF feeds the document from the top page of the document stack on the table.
The pick-up [A] and feed roller [B] feed the original into the scanner, and the separation roller [C] helps to feed one sheet at a time. Then, the R0 [D], R1 [E], and R2 [F] rollers feed the document through the scanner.
At the time of scanning the document, the scanner moves down to the scanning position under the exposure glass [G]. The shading plate [H] pushes the document to the exposure glass at the scan line, so that the document is within the image sensor’s range of focus.
After scanning, the ADF feeds out the document onto the platen cover, and the scanner moves back to its home position at the right end of the scanner.

The contact image sensor (CIS) assembly [A] consists of an exposure glass [B], a roof mirror lens array [C], a xenon lamp [D], and an image sensor [E]. The CIS moves under the exposure glass when scanning a book original, or stays at the ADF scan line when scanning a sheet original using the ADF.
The image sensor is a row of 4096 photosensitive elements (B4 width x 16 dots/mm). The roof mirror lens array focuses the light reflected from the document onto the image sensor.
Because of the short optical path inside the CIS, the focal depth is much shorter than for a CCD type scanner. Because of this, two springs at each end of the CIS push it against the exposure glass [F], so that the distance from the original is kept the same all the time. However in book scanning mode, if the original is out of the CIS’s focal range, the scanned image may get darker.
Because the analog output signal is a sawtooth waveform, data sampling timing should be adjusted whenever a new CIS is installed in the machine.

Reduction
This model uses a contact image sensor instead of a CCD. This removes the necessity of the complicated adjustments needed for a CCD scanner.
There are 3 main chips on the main control board as shown. This model uses a new type of halftone processing chip. The new halftone processor enables the use of Letter/Photo mode in addition to Letter and Photo modes as the Type of Original selection. In Letter/Photo and Photo modes, error diffusion processing is used. This produces better copy quality halftone images.
Detailed
Descriptions
The new halftone processor also includes the A/D conversion function, not only the image processing functions. The thermal head drive function is built into a chip (GA2) on the main control board. Therefore, this model does not have a A/D conversion board and thermal head board.
2-21
Page 94
OPTICS/IMAGE PROCESSING 1 November 1996
2.1.2 A/D Conversion Processing
The analog signal from the contact image sensor is converted into a digital signal that represents 64 grayscale steps. This process is just like in the other models, however it is carried out in the halftone processing chip while the other models use a separate A/D conversion board.
Shading Distortion Correction
The image data from one main scan line does not exactly represent the line from the original image, because of the following reasons:
1) Loss of brightness towards the ends of the exposure lamp.
2) Variations in sensitivity among elements of the contact image sensor
3) Distortions of the light path
Such distortions in the image data are corrected when they are converted into digital data.
Before scanning the document, the scanner reads the white plate on the back of the original scale. The output of each contact image sensor element is changed to a 6-bit digital value and stored in the shading distortion memory.
To change the analog shading distortion signals to digital data, a scale of 64 steps is made between the whitest level when the white plate is scanned and 50% of the whitest level. Using this scale, the analog signal is changed to 6-bit digital data.
While an original is scanned, the 6-bit shading distortion value for each pixel is sent in series from memory to the D/A converter, synchronizing with the image signal being sent to the A/D converter. The D/A converter changes the distortion value to an electrical current. The current is converted to the voltage to be used as high reference data for A/D conversion. In this way, the high reference voltage for A/D conversion is changed sequentially for each pixel depending on the shading distortion data for that pixel.
2-22
Page 95
1 November 1996 OPTICS/IMAGE PROCESSING
Original Background Correctio n
When an original is scanned, the whitest level of the original background is stored, and that level is used as the white peak level for A/D conversion. The grayscale is made based on the white peak level of the original. As a result, dark background does not appear on the printout.
If the original background correction is disabled, the whitest level when the white plate is scanned is used for the high reference voltage.
Detailed
Descriptions
Peak Hold
The peak hold circuit holds the voltage for the white peak level. Before scanning an original, it holds the white peak voltage from the white plate to make shading distortion data. When the original is scanned, it stores the white peak level of the original for the original background correction.
NOTE:
The white peak level is checked 5 mm from the leading edge of the original set on the exposure glass (and from the central 147 mm width). If the original leading edge is not flush with the original scale and the platen cover stays open, insufficient voltage will be input as the white peak level. If insufficient voltage is detected, a fixed voltage is used as the white peak level to avoid a faint image copy.
2-23
Page 96
OPTICS/IMAGE PROCESSING 1 November 1996
2.1.3 Binary Processing
In the halftone processing chip, the 6-bit digital signal data is generated in the A/D conversion circuit and is sent to the binary processing circuit. At that time the data is inverted to match the binary processing circuit. Therefore, the white peak level becomes 0, and the black level becomes 63.
In the binary processing circuit, the 6-bit data is converted into 1-bit data for black or white pixels. The binary process for the letter mode is different from that for the photo mode and the letter/photo mode as follows:
Letter Mode: MTF (Modulation Transfer Function) Correction Photo Mode: Error Diffusion Processing
Data Compensation Processing
In this process, the 6-bit data are converted based on a compensation curve (γ curve) which corresponds to selected image settings. For example, if a darker image is selected, a compensation curve which converts each pixel value to a higher number is selected. The output data is also 6-bit.

1 November 1996 OPTICS/IMAGE PROCESSING
MTF Correction
When the original image is converted to electrical signals by the contact image sensor, the contrast is reduced. This is because neighboring black and white parts of the image influence each other. This symptom is typical when the width and spacing between black and white areas are narrow. MTF correction counters this symptom and emphasizes image detail. The value of a target pixel is modified depending on the value of surrounding pixels. The modified data are compared with a threshold level. This determines if the pixel is to be black or white.
The value [E] of the target pixel [e] is calculated with the following formula:
Detailed
Descriptions
E = e +2
a+b+c+d+f+g+h+i
e –
 
8
  
After the MTF correction is done, the corrected data are compared with the black or white threshold level. If a pixel value is above the threshold level, it is set to black. If the pixel value is equal or below the threshold level, it is set to white. The threshold level depends on the selected density setting.

OPTICS/IMAGE PROCESSING 1 November 1996
Error Diffusion
Error Diffusion is used to reproduce halftone images in Photo mode. Before a 6-bit image signal is converted into a single-bit signal based on the
threshold level, there is a difference between the image signal value and the complete black value (63 for a 6-bit signal) or white value (0). With the Error Diffusion process, the difference is distributed among the surrounding pixels. (The MTF process simply erases these differences.)
When considering Error Diffusion in one dimension only (across the page), the 6-bit data shown in the example below produces white and black data output as shown below. In practice, this one-dimensional Error Diffusion is done in all directions on each pixel (across the page, down the page, etc.).
Image data from one scan line
7 11132130384144
In each dimension, the difference between the pixel value and the nearest extreme (0 or 63) is transferred to the next pixel. The 1st pixel in the row becomes either black or white, whichever is closest. Then, for the 1st pixel above, the difference between 7 and 0 is added to the 2nd pixel. The value of the 2nd pixel, which is now 18, is then added to the 3rd pixel. The 4th pixel becomes 52, which is closer to 63 than 0. In such cases, the difference is subtracted (not added) to get the next pixel value. In this example, the difference is 63-52=11, and the next pixel value (30-11) becomes 19.

Binary Processing in Letter/Photo Mode
In the Letter/Photo mode, the machine checks each pixel of the original to see if the pixel is in a line area or in a photo area. To recognize a line area in a photo original, the CPU does the following calculation on the 6-bit pixel data.
x = | (c + f + i) - (a + d + g) | y = | (g + h + i) - (a + b + c) |
If x or y is greater than 10, the machine recognizes that pixel e is in a letter area of the image and uses the MTF process to convert the 6-bit value to 1-bit.
Detailed
Descriptions
If the calculated number is 10 or less, the pixel is converted to 1-bit using Error Diffusion.
To emphasize characters in a photo original when using Letter/Photo mode, a data compensation curve (γ curve) is used to make a darker image.

80% Redu ction
140% Enlargement
Reduction and enlargement in the sub-scanning direction is done by changing the original transport motor speed. Reduction and enlargement in the main scanning direction is handled by the magnification and image shift processing.
Pixels for scanning and master making are generated at fixed intervals (the contact image sensor and thermal head element intervals). The image is scanned at the contact image sensor element interval. If pixels on the master are made at the same interval (by the thermal head elements) then the master image is the same size as the original.
80 % Reduction
For example, data for 10 pixels in a main scan line are scanned by the contact image sensor. Those data are compressed into data for 8 pixels by the magnification processor. As a result, the image is reduced to 80 %.
140 % Enlargement
Data for 10 pixels of a main scan line are expanded into data for 14 pixels. As a result the image is enlarged with a 140 % magnification ratio.
When actual pixels are divided in accordance with a magnification ratio, the values of the imaginary points that would correspond to new pixels are calculated by the magnification processor. The proper value for each imaginary point is calculated based on the image data of the surrounding pixel values.
