Chapter 1 Caution for work
1.2 Countermeasure for static electricity when replacing and maintaining the electrical parts
If an electronically charged human body touches electronic parts like PCBs, it may adversely affect the electronic parts. When handling the electronic parts, be sure to use static-dissipative conductive gloves to prevent the components on the PCB from being damaged due to static electricity. The static-dissipative conductive gloves are included in the spare parts of your machine.
When using the static-dissipative conductive gloves, be sure to turn off the air brake and wait 15 seconds to carry out operation.
1.3 Handling chemicals
The work with the machine involves the handling of slightly poisonous, irritating and etching substances, to apart from this, the user must ensure sufficient aeration. The air in industrial workrooms should be exchanged at least 8 to 10 times per hour. All photographic developers contain substances which may irritate the skin, the mucous membrane and the eyes and which may cause allergic skin reactions affecting very sensitive persons. For this reason, avoid long or repeated skin contact, especially with developer solutions. For all jobs where photographic processing solutions may splash, e.g. preparing and filling in chemical solutions, cleaning processing racks etc.:
ˇ
Wear protective gloves, rinse all solutions that get on the skin with plenty of running water. Wear industrial glasses. Wash with soap and rinse with lots of water after completion of work.
ˇ ˇ
Store chemicals and processing solutions in a safe place. If a processing solution has been ingested accidentally, immediately rinse the mouth out with water, and drink 1 or 2 cups of water. Contact a physician as soon as possible, and then vomit the solution according to the physician's instructions. If processing solution gets into eyes, immediately rinse them under running water for at least 15 minutes, and then contact a physician. Processing solution stains on your clothing may result in discoloration for fading, when handling processing solutions, wear clothing for work wear.
Chapter 1 Caution for work
Photochemical are not allowed to be drained off into the public sewage system! Please obtain the information about the regulations in force about the handling and correct disposal of chemistry from the country's authorities in charge.

Chapter 2 Maintenance
2.3 Double exposure center calibration
DL-1210 does double exposure for 152x102mm and 127x89mm formats automatically. For a better understanding of double exposure, you can send 2 copies of 152x102mm format (152mm paper width) in Istudio and then open the printer door to watch the exposure procedure. Usually this calibration has been done in the factory, no need to do again by the user. Purpose: To calibrate the image exposure center of the 152x102mm or 127x89mm photos which are printed by double exposure mode, this calibration shall be performed when white border appears on these photos while the ABCD calibration has been completed for the corresponding formats. Precondition: The ABCD calibration has been completed for the corresponding format. Steps: Open Maintenance, and then click service.
Fig 2.3.1 On Other tab under Offset separator photos select the format to be calibrated.
Chapter 2 Maintenance

Chapter 2 Maintenance
2.5 Twister 4 calibration
A photo printed by DL-1210 is composed of pixel matrix. DL-1210 uses a 1280×1024 resolution LCD for making image, so that by each time exposure, there will be a 1280×1024 pixel matrix come into being on the photo. Actually this resolution is not good enough for the photographic business, so that DL-1210 use 4 times or 9 times exposure technology to expose 4 times or 9 times for each photo (Fig 2.5.1), a 2560x2048 or 3840×3072 pixel matrix will come into being on the photo finally. During each time exposure the information on the LCD is different.
Fig 2.5.1 The position of each time exposure is controllable, the final result of the photo must be compose of a uniformly distributed pixel matrix, if 2 pixels are close to each other too much then there will be a overlapping effect so that it will come up the tiny horizontal or vertical lines or grid lines on the photos. Purpose: To remove the strong grid lines of the photos which are printed by 4 times exposure mode, in the case the grid lines appear on these photos after several months, this calibration shall be performed. Tools required:
ˇ ˇ
Magnifier (at least 8X) 127mm or 152mm glossy paper
Steps: 1. Initialize the twister 4 data in the Linux Registry. On the DL-1210 machine Windows PC click Run. Key in \\10.1.1.1\win-software. Run Iregedit.

Fig 2.5.6 01X, 02X, 02Y, 03Y each corresponds to a group of 3 lines, all of them must be distributed symmetrically. Assume that the 02Y corresponded to the following group of lines:
Fig 2.5.7 The middle line is not in the center of the other 2 lines, accordingly it shall be moved rightwards to get this 3 lines distributed symmetrically. In this case in the Linux registry etc/twister/advanced the value of 02Y which shall be increased like: +10.
19
Click save now.
Chapter 2 Maintenance
On the contrary, decrease the value if the middle line shall be moved leftwards.
Complete the adjustment for the other 3 groups of lines, the method is similar. Go back to Sendp, click Go! to send a new test print, repeat the above adjustments until the result is good. 4. On the below district of the test print, observe the joint point between the 01Y 02Y line or the 02X 03X line and the square by magnifier.
Fig 2.5.8 The ideal result shall be as Fig 2.5.8 (magnified and take the joint point between the 01Y 02Y line and the square for example):
Fig 2.5.8 Usually there are two lines beneath the 01 02Y line, the density of these 2 lines shall be the same, otherwise the 01 02Y line shall be moved to the direction of the stronger line. Assume that the density of the left line is higher than the right line, then the 01 02Y line shall be moved leftwards. the left side of the 01 02Y line is a sign -, therefore in the Linux registry etc/twister/advanced/ the key 01Y and 02Y shall be decreased the same value in the meantime, such as: -2 or -5. Click save now.
Chapter 2 Maintenance
The adjustment methods of 02X and 03X is similar.
20
Go back to Sendp, click Go! to send a new test print, repeat the above adjustments until the result is good. For user, usually no need to do the step 1 and the step 3, just complete the step 4 base on the current data is OK.

2.6 Twister 9 calibration
9 times exposure mode offer a higher resolution for the photos which are printed by the lens 000 such as 203x152mm and 203x305mm formats than 4 times exposure mode, at the same time the exposure time is longer.
3.21 Lens selection logic If High Quality has been selected when creating a format in Maintenance, this format will be printed by 9 times exposure mode (Fig 2.6.1).
Fig 2.6.1 Purpose: To remove the strong grid lines of the photos which are printed by 9 times exposure mode, in the case the grid lines appear on these photos after several months, this calibration shall be performed. Tools required:
ˇ ˇ
Magnifier (at least 8X) 203mm glossy paper
Steps: 1. Minimize the horizontal grid lines.
Chapter 2 Maintenance
The twister 9 data is located at etc/twister/09 in the Linux Registry (Fig 2.6.2).
22
Fig 2.6.2 By adjusting the value of 3X, 4X, 5X and 6X, 7X, 8X, the horizontal grid lines can be minimized. Prepare ring around test data. For a better understanding, see Fig 2.6.3.
23
Chapter 2 Maintenance
Fig 2.6.3 In the Linux Registry, modify the value of the 3X, 4X, 5X and the 6X, 7X, 8X as the table below, after each time modification, save the data to Windows PC: Data # 0 1 2 3 4 5 6 7 8 03X 04X 05X value modification 0 +1 +1 0 -1 -1 -1 0 +1 06X 07X 08X value modification 0 0 +1 +1 +1 0 -1 -1 -1
For example, the data ID 1 is a new data after modification base on the data ID 0. The 3X, 4X, 5X must be modified the same value in the mean time, same as the 6X, 7X, 8X.
Chapter 2 Maintenance
24
To save the data to Windows PC, highlight 09, right click mouse and then select export... (Fig 2.6.4):

Fig 2.6.6 Open Istudio, load a portrait photo, and select a 9 times exposure format for example 203x152mm HQ.
Chapter 2 Maintenance
26
For saving the paper, you can create a temporary format 203x89mm HQ for this calibration. Import the data files 0 to the Linux Registry (Fig 2.6.7 and Fig 2.6.8).
Fig 2.6.7
Fig 2.6.8 Click Open. In Istudio click Send button to send a test print.
Wait until the exposure finish. Repeat the above steps to send test prints for each data ID.
27
Chapter 2 Maintenance
After the test prints coming out, mark the corresponding ID on the paper immediately. Make comparison of the test prints, pick up the best one. If still the result is not satisfied:
ˇ
Go back to step 1 to try to make more test data files and the test prints (so that the method of this calibration is called ring around). Try to make 2 or 3 value modifications instead of 1 for each time modification of the 3X, 4X, 5X and the 6X, 7X, 8X in the Linux Registry.
ˇ
Import the corresponding data file of the best test print to Linux Registry. 2. Minimize the vertical grid lines. By adjusting 01Y, 05Y, 07Y and 02Y, 03Y, 08Y value, the vertical grid lines can be minimized. The method is similar as above. Finally delete the temporary format 203x89mm HQ in maintenance if you created it, otherwise the morning setup will use this format for the printing and then come up the wrong result.
Chapter 2 Maintenance 2.7 Uniformity calibration
28
Purpose: To calibrate the uniformity of color or density to be the same at each district of the photo.
Imagine if you printed a photo from a neutral grey test film or a neutral grey test file, the result shall be uniform neutral grey at each district of the photo, which means the density uniformity result of the photo shall be good. Usually there is a diffuser(mirror box) in film minilab, of which the function is to convert the diffusive light emitted from halogen lamp into coherent light (parallel light), so as to get an uniform neutral grey photo. DL-1210 does not have diffuser in it however the density uniformity result of the photo which is printed from a neutral grey test file is also perfect. This attributes to that DL-1210 adopts software control the transmissivity of each LCD liquid crystal particle which is on LCD to simulation the effect of diffuser. Mask file records the transmissivity correction of the LCD liquid crystal particles, of which the file extension name is prn. So that the Mask file is a virtual diffuser.
Fig 2.7.1 Mask file is a total compensating result of exposure unit. DL1210 have 2 lenses so that there are 2 Mask files needed for the printing for each lens (Fig 2.7.1). The Mask file shall be re-calibrated when the following event occurs:

Print sample photos to compare the color between the photos and the monitor preview, if still not satisfied, use Cassette balance or Master balance for ultimate control.
The color could be managed from monitor to photos but they could not be 100% the same. The photos and the monitor explain the color in different way, usually the photos are more brilliant than the monitor preview since the photos belong to another color space which is bigger than sRGB and the color has been transferred to a wider range than sRGB during the printing and processing.
ˇ
To use Cassette balance: Run Maintenance. Select Cassette balance and then click Next. Select cassette number and then click Next. Change the values of C, M, Y, D, for example: + or -0.01. Click OK.
