A check prints too high or too low for four main reasons: the layout position does not match your paper (top versus middle versus bottom), the page is being scaled, the paper size is wrong, or the printer feeds the sheet with a small offset. Measuring how far off the print is tells you which cause you have.
This page covers vertical errors only. For left and right problems, see Check Prints Too Far Left. For a symptom-by-symptom troubleshooting list, see How to Fix Check Printing Alignment.
Measure first: how far off is it?
Print a test on plain paper, hold it over a sheet of your stock against a light, and measure the gap between where a line should be and where it printed. The size of the error is the best clue. Use the table as a guide, not a rule.
| Size of the error | Most likely cause | Where to look |
|---|---|---|
| About 3.5 to 4 inches | Wrong layout position (top, middle or bottom) | Your layout or position setting |
| About 0.5 to 0.7 inch, grows toward the bottom | A4 instead of Letter, or scaling below 100% | Paper size and scale in the print dialog |
| Under about 1/4 inch, steady | Margin or feed offset | Printer, tray, alignment nudge |
| Small and different on each sheet | Loose guides, worn rollers, unsquared stack | Paper tray and feed |
Cause 1: The layout position does not match your stock
On 3-to-a-page stock, an 8.5 x 11 sheet holds one check and two stubs. Top, middle and bottom describe which third carries the check. A check is about 3.5 inches tall, so if your software prints a top check on middle stock (or the reverse), it lands roughly one third of a page, about 3.5 to 4 inches, away from where it belongs.
This is the cause to check first when the error is large. Compare your stock to your software: which third has the perforated check area? Then set the same position in your software. The difference between the formats is explained in Top Check vs Middle Check Paper, and the sheet itself is covered in What Is 3-to-a-Page Check Paper?.
Cause 2: The page is being scaled
If your print dialog is set to Fit to page, Shrink to fit or any percentage other than 100%, every dimension changes. The error grows with distance from the top edge. For example, at 95%, content 8 inches down the page moves up by about 0.4 inch, while content 1 inch down moves by only 0.05 inch.
That is why scaling often shows up as a check that is fine at the top and low or high at the bottom. Set the scale to 100% / Actual size, then print again before you change any alignment value. If you print from a browser or PDF viewer, make sure the viewer is set to Actual size too.
Cause 3: The paper size is wrong
US Letter is 11 inches tall. A4 is about 11.7 inches tall. If the printer or application is set to A4 while you load Letter, the content is positioned for a taller page and sits about 0.7 inch off, and the printer may also scale it. Set US Letter in both the application and the printer properties.
Check the printer driver as well. Some drivers keep their own default paper size and ignore the application's choice.
Cause 4: Margins and feed offset
Every printer has a non-printable area and its own feed behavior. The sheet is pulled in by rollers, and where they grab the paper changes where the print starts. Headers and footers added by a browser also shift content down, and options such as auto-margins or borderless printing can move it again.
These produce smaller, steady errors of a fraction of an inch. They are the ones you correct with an alignment nudge. Turn off headers and footers, square the stack, snug the tray guides, then move the whole page up or down in small steps.
Cause 5: Different trays and paper types
A printer may feed from different trays with different distances, and choosing a heavier paper type can change how far the sheet travels before printing starts. A test on plain paper from tray 1 does not always predict a run of heavy stock from a rear slot. Test using the same tray and paper-type setting you will use for real checks.
How to correct it, in order
- Confirm that the layout position (top, middle, bottom) matches your stock.
- Set paper size to US Letter and scale to 100% / Actual size in both the application and printer.
- Turn off headers, footers and automatic margins.
- Load a single squared sheet using the same tray and orientation each time.
- Print on plain paper, hold it to the light over your stock and measure the remaining error in fractions of an inch.
- Nudge the page in the opposite direction in small steps. If the check prints too high, nudge it down.
- Test again, then confirm the MICR line and the stub area are still where they should be.
Change one thing at a time. If you adjust position, scale and margin together, you will not know which fixed it. For the complete hold-to-the-light method, follow How to Align a Check on Blank Check Paper.
Why a vertical shift matters more near the bottom
A check is only about 3.5 inches tall, and the MICR line sits in a narrow band along its bottom edge. A vertical shift that looks minor on the amount box can push the MICR line off its band or into the perforation. Always recheck the bottom of the check after any vertical adjustment.
In Check Writer 123 you choose the check position (top, middle or bottom) for 3-to-a-page stock, and the alignment tool can nudge the whole page up or down, with the MICR line adjustable separately. Test Print is free and never counted, so you can try each fix without using a real check.
Putting it together
Measure the error, match it to the table and fix the largest cause first. A third-of-a-page error is a layout position problem. A half-inch error that grows down the sheet is paper size or scaling. A fraction of an inch is a margin or feed issue you can nudge away. For printer-side settings, see How to Print Checks Using a Regular Printer.
