Epson FX Emulation
Forms and Tractors
The FormsPro 4503 contains three sets of paper tractors (front, center, and rear). It is possible, via software, to change to a different set of tractors and continue printing.
You may change to a different set of tractors by selecting a different form. The "Path:" value in the "Setup: FORM" menu specifies "Front", "Center", or "Rear" for each form that is defined. When a form is selected, the associated set of tractors is also automatically selected.
Load Form | ESC EM n |
Causes the current line to be printed, and then loads paper and form parameters for form n. 0³n³2. If form n is already loaded, this sequence is ignored. If not, the current form will be unloaded, the parameters for form n will be selected, and the printer will go offline to wait for the operator to install the new form and place the printer back online. In the FormsPro 4503 the same happens unless selecting form n also selects a different paper path. In that case, the current form is unloaded, the tractors are moved to engage the new path, the new form is loaded, and printing may continue.
The printer will not unload the current form if a previously printed form has not been torn off. In this case, the printer will go offline, sound the bell, and display the message "Tear Off Paper". When an operator tears off the paper and places the printer back online, the printer will unload the current form and continue.
If the printer is unable to load the new form, it will sound the bell and display the message "No Paper to Load". A "Paper Out" error will occur and the printer will go offline to wait for an operator to clear the error.
Example: The following escape sequence will load form 2.
Escape Sequence: | ESC | EM | 2 |
Hexadecimal: | 1B | 19 | 32 |
