WellPrintEXP -- EPSON TX800-12H user manual

English OEM user manual for the WellPrint EPSON TX800-12H flatbed printer control system from Shanghai Rainbow Industrial Co., Ltd. (WellPrint brand). The PDF is 42 pages; its own page footers count "1 of 34" up to "39 of 34" because the fault section was added after the cover count. It covers the W801TOA3_VA USB 3.0 mainboard, the W803HDON_VA head (spray) board and W802HEND_VA XP600 gusset board, the external touch panels, startup initialization with the USB boot action tool, head ink order and supported resolutions / PASS counts, the WellPrintExp software (gear-ratio, cleaning, head status, vertical, step and bi-directional calibration, loading PRN files, every menu and setting page) and a common-fault table.

It is different from AM.CO.ZA PrintEXP (manuals/printexp/). No prices or stock are stored on this page.

Manual content (full English text, condensed)

1. Board instructions

1.1 W801TOA3_VA mainboard interfaces

The manual shows a photo of the board, then lists the connectors:

All limit inputs are wired, from left to right, +5 V, GND, signal. (The manual uses the label J5 both for the X motor and, on a second photo, for the USB port.)

1.2 Mainboard notes

1. The board runs from 24 V and 42 V at more than 5 A. A two-stage filter on the 220 V input of the power module is recommended.
2. Ground the board reliably. Fixing screws must make full contact with the case, the case must be bonded to a real earth, and the middle (earth) pin of the machine's power socket must be properly earthed.
3. Room temperature for the machine 15 to 30 °C; the board itself tolerates 0 to 75 °C.
4. Keep air moving around the board so heat does not hurt print quality or damage it. Floors should be easy to clean and free of dust and static.

1.3 W803HDON_VA head board (called "spray plate")

1. JP3 raster (linear encoder) decoder port, left to right +5 V, B, A, GND.
2. J2 origin left limit and J3 origin right limit (each +5 V, GND, signal).
3. J4 standby (spare) port.
4. Secondary ink supply port.
5. (Unlabelled in text.)
6. +42 V power input; watch the polarity.

1.4 W802HEND_VA XP600 gusset plate

XP600 29-pin double-head adapter board; the head data cables connect on the same side. (The page also shows the W801PANE_VA key board, labelled in Chinese.)

1.5 External touch panel

Two screens are used: a 4.3-inch display controller and a Kunlun Tongtai 7-inch panel. Both show the same main screen. When a touch screen is used, a small adapter board connects to the mainboard and the screen connects to it with an RS-232 direct (straight-through) data cable.

1.6 Startup initialization (USB boot action tool)

1. Power the board, then install the USB driver. When the tool shows "connected", you can set parameters.
2. Click Load file, choose the parameter file prepared by the technician, then Download to write the boot parameters into the board.
3. Origin fine tuning: after power-on, load the file first, open the initialization action page, set speed and travel distance, and move left / right until the head lines up with the platform. Click Set, return to the firmware page, click Download, then restart the machine.

Note: the 3.0 board ships with parameters set for the customer's machine model. The tool is normally only needed when parameters do not match the machine or the origin needs fine-tuning.

2. Head ink sequence

• Head colour order: four-colour, channels 1 to 6 = K, C, C, M, M, Y. Six-colour, channels 1 to 6 = K, C, M, Y, LC, LM.
• Colour offset: shown as a diagram in the PDF (see also Basic setting, Colour Offset, below).

Supported resolutions and PASS counts

3. Software instructions

3.1 Home screen

After the board has been initialised, connect it to the PC with the USB cable, insert the dongle and open WellPrintExp. The printer status at the bottom left then shows "high" (connected).

3.2 Debugging steps

Calibrate the X gear ratio (Maintenance, Motion setting):

1. Type a small value (100) next to Move and click Move. The carriage position appears at the bottom left. If it shows a negative number the raster decoder polarity is reversed: swap the decoder A and B lines and restart the machine.
2. Click Reposition, enter about half the print width, click Move, and click Reposition when it stops. Then enter the full print width, Move and Reposition.
3. For the feed (Y) ratio: mark the material, enter 100, click Move, mark the material again, measure the real distance with a ruler, type it into Run length and click Calculate (click Calculate only once per move). Repeat with 300 and then 600.
4. Click Apply at the bottom of the page to save.

Cleaning option (Maintenance, Cleaning option). The cleaning cycle runs in this order, each step set in pulses:

1. Ink pad (capping station) down to the lower limit.
2. Pad up against the head to absorb ink.
3. Ink pump starts (pump time set in the tool).
4. Wait for the air pressure in the pad to balance so ink is not sucked back (set in the tool; keep it above 3 seconds).
5. Pad down to the lower limit.
6. Pump empties waste ink from the pad.
7. Carriage moves left to the wiping (scraping) position for head 1.
8. Platform up to wiping height.
9. Wiper moves out under the head.
10. Carriage moves across the wiper.
11. Pad down to the lower limit.
12. Wiper returns.
13. Carriage returns.
14. Pad up to the flash (spit) position.
15. Head flash-jets.
16. Pump empties waste ink.
17. Pad down to the lower limit.
18. Pad up to standby height.

Head status: on the home screen click Test, then Head status, and print the nozzle check.

Vertical calibration: Test, Vertical calibration. If the lines lean one way, adjust the head "left front push, right back pull"; if they lean the other way, "left back pull, right front push". Repeat until the pattern is straight.

Step calibration: Maintenance, Bias calibration, Step calibration, Print. Choose Base step and print. If the lines overlap at, for example, -6, type -6 in Revise and click Apply. Print again until the overlap is at 0 every time. Pick each PASS count from the Base step drop-down and calibrate it the same way.

Bi-Dir offset: Maintenance, Bias calibration. Choose the resolution (default 360), choose the speed and adjust the slow, normal and fast values, then Print. If the top and bottom marks line up at 6 at normal speed, the offset is -6: enter -6 and Apply, then print again until they align at 0. Resolution to calibrate for each mode:

3.3 Loading a print file

Three ways:

1. Open in the main menu bar and pick a ripped PRN file.
2. Task Choice in the menu bar, browse to the RIP output folder and double-click the file.
3. Print straight from the RIP software with the port set to 127.0.0.1.

Double-clicking a task opens Task properties:

• Repeat printing: after each copy the carriage returns and the same PRN prints again from the margin start position.
• Multiple setting: set copies across and along, with a gap in mm.
• Area printing: print only a selected part of the file (repeat and multiple settings are ignored).
• Ink count: ink needed for this PRN file.
• Ink volume control (under Task Choice): reduces ink for the current PRN. Reducing ink here lowers output resolution and coarsens dots, so it is not recommended.

Click OK to import, then Print. The screen shows the PRN's colours, area and other details.

3.4 Title menu bar

3.5 Print control page

• Margin width: start position in X. Jog the carriage with the keypad and click Set to make the current position the start.
• Colour bar: prints a colour strip (width, distance to image, left / right / both set on the Parameters page).
• Print queue: with several PRNs imported, prints them all in turn.
• Print speed: slow, normal or fast (values set in Maintenance, Motion setting).
• Print direction: to-left, to-right or bi-direction (calibrate Bi-Dir first).

3.6 Parameters page

• White-ink setting: for photo-machine use only spot colour or white-only types are used. Leave the white channel counts at the software defaults; raise white-ink repeat times to thicken white.
• Colour bar print: width, distance to image and position.
• Eclosion (feathering): tick it and normally choose type FOG. A higher level is slower but looks better. Use it for solid colour blocks or when the head is not in perfect condition.
• Auto cleaning: for example after every 10 PASS the carriage returns to origin for a quick flash at frequency 512.
• Flash jetting: standby flash. With Is Standby Flashed ticked it spits at intervals; standby and flash times are usually 4 to 16.
• Other settings: feeding speed (value set in Maintenance, Motion setting, Y-Moto), feed the material forward after the PRN finishes, and Skip white (skips empty areas in X and Y; works when the colour bar is ticked).
• Load-ink: choose head 1, head 2 or both. The capping station rises and the pump runs until you click Stop.

3.7 Maintenance page

Bias calibration: print the Bi-Dir charts at 180 and 360 resolution for slow, normal and fast speeds, and print Step calibration for each PASS count you use. The head-to-head setting is only used with two heads; with one head select PrintHead1.

Motion setting:

• X-Moto configuration: sets the slow / normal / fast print speeds. Fast must not exceed the head's firing frequency; 5th- and 7th-generation heads support up to 1200 mm/s at 360 dpi.
• Reposition speed: carriage speed when Home is clicked. Return speed: carriage return speed in one-way printing. Move / Reposition: used for X gear-ratio calibration.
• Y-Moto configuration: slow / normal / fast feed speeds. Faster feeding gives smoother printing as long as the motor does not stall or lose steps.
• Move / Calculate: used for gear-ratio calibration.
• Click Apply after any change or it is lost.

Voltage setting: Voltage Offset from -6 to +6 changes the waveform voltage to make ink dots bigger or smaller. Enter the value and click Setting; the software pauses briefly while it writes to the board.

Basic setting:

• Base step value: default 360; normally leave it.
• Position offset: X-Offset so that margin 0 lands exactly at the material edge. Y-Offset means the same in Y but is not used on photo machines.
• Acceleration distance: larger is gentler, smaller is faster but can make the motor jitter. In Y the steps are short, so keep it small, 3 to 8.
• Colour offset: channel ink order must match the head's ink order. When changing it, keep the two channels of one colour together (for example CCMMYYKK or MMYYCCKK, never KCMYMCK).
• Click Apply to save.

3.8 System menu

• Head status and vertical calibration are the same as on the menu bar.
• When everything is set up, click Setting factory parameters to save a backup copy. If settings go wrong later, click Restore factory parameters.
• Dongle manager: a time-limited (staging) dongle needs a password entered to keep working.
• About WellPrintExp: shows the board's firmware and logic versions (only when connected).

3.9 Other status information

Connection status ("high" when connected), flash on / off, live carriage position, an error bar with a ? button that opens the message history, and a progress bar for the current PRN.

4. Common fault handling

AM practical notes

• Calibrate in this order on a new install or after a head change: gear ratio, head status, vertical, step (each PASS you use), then Bi-Dir for each speed and resolution. Save with Setting factory parameters once it prints well so you can restore later.
• Most "software not online" calls are the dongle, the USB driver or a mismatched software build. Use the WellPrintExp build that matches the board and head (see the software notes below).
• Keep the capping station healthy. The related part in the buythis dump is F-INK/CAP/TX800, an Epson TX800 / XP600 printhead cap kit: F-INK/CAP/TX800.
• The board needs 12 V, 24 V and 42 V. The buythis dump lists AE-POWER/SMPS350, a 12 V / 24 V / 36 V / 42 V integrated power supply for flatbed UV printers: AE-POWER/SMPS350. Check the connector and wattage against your machine before swapping.
