Citizen GSX-140 Paper Handling

Standard Feeders: Push tractor feed, Pull tractor feed, Friction feed.

Optional Feeders: Automatic Sheet Feeder: Permits continuous printing on cut sheets.
Manual Sheet Feeder: Permits stacking multiple cut sheets.

Continuous Feeding

Loading fanfold paper (rear push feed)

1. Place your fanfold paper stack below or behind the printer so that the paper may feed in from the rear of the printer.

2. Unlock the tractor feeders by pulling the lock levers forward. Slide them left and right to the approximate paper width. Lock the left one in place.

3. Flip open both tractor feeder covers and position the paper's left sprocket holes over the tractor pins on the left tractor feeder. Snap it closed. Position the paper's right sprocket holes over the tractor pins on the right tractor feeder and snap it closed. Move the right tractor feeder gently until the paper is just taut between the two feeders. Re-lock the lock lever.

Look at the paper's edge and be sure it is straight. Paper which enters the printer askew or off-center can cause a paper jam.

4. Set the paper select lever to the forward position, where the icon shows a stack of paper.

5. Install the paper guide/sheet separator in the sheet separator position. Do this by engaging the small extensions on the lower left and right corners of the paper guide onto the small posts pointing into the printer. Be sure you are using the higher of the two posts on each side.

Recline the paper guide backward. Simultaneously the front end of the paper guide will slide forward slightly. The small extensions will rest on top of the second set of posts which point into the printer. Correctly, installed, the paper guide will incline about 15 degrees.

6. Move the paper holders from the sides into the middle of the paper guide. This prevents your printed output from becoming accidentally jammed in the paper guide on it way out of the printer.

7. Turn on the printer.

8. Push the [PARK LOAD] key. This will advance the paper to the starting print position.

9. Press the [ON LINE] key.

Loading fanfold paper (bottom pull feed)

Use this feed for continuous forms such as multi-part forms and card stock.

1. Be sure the tractor is in the pull position.

2. Turn off the printer before loading the forms in the from the bottom.

3. Remove the top cover.

4. Set the printer on it rear side.

5. Insert the forms through the slot in the bottom of the printer. Pull the forms through so that 4 or 5 inches extend out of the printer.

6. Set the printer right-side-up again.

7. Open the tractor feeder covers, position the forms on the sprockets and close the covers. Be sure the paper is straight. Adjust the distance between the tractor feeders, if necessary, by unlocking the lock levers and sliding the feeders until the paper is taut. Relock the levers.

8. Move the paper select lever to the forward (paper stack) position.

9. Turn the paper feed knob clockwise until the second sheet of the forms is at the correct starting print position. When printing with the tractor in the pull position, the first sheet of the forms is unusable.

10. Set the paper thickness lever to +1 for 2-part forms, +2 for 3 or 4-part forms.

11. Replace the top cover, pressing on the "push" locations. The transparent part of the cover will rest against the tractor unit.

12. Turn on the printer.

Manual Feeding

Automatically loading single sheets

1. Be sure the tractor is in the push position.

2. Install the paper guide in the upright position used for inserting paper. To do this, hold the paper guide so that the two corner extensions point downward into the printer. Hook the extensions onto the upper guide pins pointing into the printer, then slide them down so that they engage the lower guide pins, also.

3. Change the paper select lever to the rear (single sheet) position.

To use the paper guide, simply set the left paper holder to either "L" (U.S. letter size) or "A4" (metric letter size), according to the size of the paper you will be using. Insert a sheet of paper and adjust the right paper holder to the paper width.

4. With the sheet of paper out of the printer, turn on the GSX 140. You will see the POWER light will light and the Command-Vue display will flash "MACRO 1" for a few seconds. Then, the ALARM light will come on and the display will change to a steady "OFF LINE/P. OUT".

5. Insert a piece of paper head-in, face-down, between the paper holders (as you would load paper in a typewriter). Push the paper down gently to be sure it is all the way in.

6. Wait a brief time (approximately half a second). The paper will automatically feed into the printer and stop when it reaches the correct position for the starting line of print. The ALARM light will go off and the control panel message will change to "OFF LINE".

7. Prepare to print by pressing the [ON LINE] key which change the display to "ON LINE".

Loading paper in Manual Sheet Feeder (the Manual Sheet Feeder is optional)

1. Move the paper setting lever (the left lever) forward.

2. Adjust the left and right guides on the sheet feeder to the size of the paper you are going to use.

3. the paper must be well fanned before stacking into the sheet feeder. This keeps the paper from "sticking" so that only one sheet is fed at a time. Approximately 50 sheets can be loaded, depending on the paper thickness.

4. After fanning the paper stack, align its edges by tapping the sides and the bottom of the paper stack on a flat surface.

5. Place the paper stack between the paper guides. Make sure the guides fit snugly but do not bow the paper stack. (When using letterhead paper, load the top edge of the paper upside down with the printed side facing backwards as you would when inserting letterhead in a typewriter.)

6. Move the paper setting lever to the rear position.

7. To load a sheet into the printer, move the sheet loading lever (the right lever) forward. This will advance the sheet halfway; then, the printer will automatically advance the sheet to the top-of-form (TOF) position.

Activation: Automatic. The interfaces work on a "first come, first served" basis; the interface that receives data first becomes the active interface and remains active until you turn the printer off and on again. When an interface is active, the other one is not used, even if data is sent while the active interface is not receiving data.

Activation: Automatic. The interfaces work on a "first come, first served" basis; the interface that receives data first becomes the active interface and remains active until you turn the printer off and on again. When an interface is active, the other one is not used, even if data is sent while the active interface is not receiving data.
