You’ve designed the perfect Christmas card, place card or menu, loaded a sheet of lovely 290gsm card, and the printer refuses to feed it, pulls it in crooked or flashes a paper-jam message. Before trying again, check whether your printer supports that particular card and which tray and settings it needs.

This guide explains what to check when printing on 250–300gsm card, and when it is better to choose lighter stock or use a professional printing service.

Please note: This article provides general guidance, not instructions for a specific printer. Always read and follow the manufacturer’s manual and current support advice for your exact model, including supported media, loading, jam clearing, cleaning and safety precautions. If that advice differs from this guide, follow the manufacturer’s instructions. If you are unsure, contact the manufacturer before proceeding.

1. Check your printer’s maximum gsm for the tray you’re using

Look in your printer’s user guide for supported paper weights, thicknesses, sizes and media types. The limits can differ between the main cassette, rear tray and manual feed. A headline maximum weight may apply only to particular media or a particular feed path.

Gsm measures weight per square metre, not thickness or stiffness. Two cards of the same gsm can behave differently in a printer. Do not exceed the manufacturer’s stated limits or assume that a setting will make unsupported card safe to use.

Not sure which weight you need? Our Paper and Card GSM Explained guide covers weights and uses.

2. Use the feed path recommended for thick card

If your manual specifies a rear feed, manual slot or multi-purpose tray for heavy media, use that route. A straighter paper path can reduce bending, but a rear tray alone does not mean a printer supports 300gsm card.

• Inkjet printers: use the tray and loading method specified for your card’s weight and finish.
• Laser printers: use only laser-compatible stock within the model’s limits. Some models specify a manual feed and rear output for thick media. Open a rear output cover only where the manual instructs you to.
• Printable side: follow the loading diagram for your tray rather than assuming the printable side faces up or down.

3. Try one sheet at a time

Where your printer’s instructions allow single-sheet feeding, start with one sheet of supported card. This helps you check feeding and alignment without wasting a whole pack. Load the next sheet when the printer is ready.

If the manufacturer permits a small stack, follow its capacity and preparation instructions. Do not force extra sheets into the tray.

4. Choose the correct media setting

In the print dialogue, open Printer Properties or Preferences and select the media type recommended for your stock. Names vary, but may include Cardstock, Heavyweight or Thick. Match the setting to the card and your printer’s instructions, rather than automatically choosing the heaviest option.

Do not substitute a photo-paper or envelope setting unless the manufacturer recommends it for that stock. Also check that the selected paper size and tray match the sheet you have loaded.

A media setting cannot increase the printer’s physical paper-weight or thickness limit.

5. Troubleshoot a paper-jam message with no obvious jam

A jam message can have several causes, including a feeding problem or a small piece of paper left in the path. Follow your model’s jam-clearing instructions before continuing.

1. Cancel the print job and follow the manufacturer’s shutdown and safety instructions. Laser printers may contain hot components that need time to cool.
2. Check only the user-accessible areas identified in the manual for scraps or damaged sheets. Do not force covers, rollers or paper.
3. If roller cleaning is recommended, use the exact method and cleaning materials specified for your model.
4. Try a sheet of supported plain paper. A successful test helps narrow down the problem, but does not rule out every printer fault.
5. Reload one supported sheet of card using the correct tray, guides and media setting.

If the error continues with plain paper, consult the manufacturer’s troubleshooting support rather than repeatedly feeding thicker card.

6. Check crooked prints and misplaced starts

Skewed prints can result from loading or feeding problems. A print starting too low can also involve document size, margins or print settings, so check those as well.

• Load the sheet to the position shown in the manual. Do not push it farther into a manual slot than instructed.
• Adjust the side guides so they touch the card without bending or squeezing it.
• Use flat, undamaged sheets with clean, square edges. Store unused card flat and dry.
• Follow the manufacturer’s roller-cleaning guidance if feeding remains uneven.
• Check the document size, paper size, scaling and margins with a plain-paper test before using your card.

7. Know when to choose a different printer or lighter card

If you regularly print wedding stationery, menus, certificates or Christmas cards on 250–300gsm stock, compare printers by their supported media, tray-specific weight and thickness limits, and paper path. Do not rely on a generic “prints on card” claim.

If your current printer does not support your chosen card, lighter stock or a professional printing service is a better option than repeated feed attempts. Test a small quantity before committing to a large print run.

Quick-fix checklist

• The card’s weight, thickness, size and finish are supported by your printer.
• You are using the manufacturer-recommended tray and output route.
• The sheet is flat, undamaged and loaded in the correct orientation.
• The paper guides touch the edges without squeezing.
• The media setting, paper size and selected tray match the loaded stock.
• Any jam clearing or cleaning follows the model’s manual.
• A plain-paper test has been checked before printing on card.

Frequently asked questions

Why does my printer say paper jam when there’s no paper stuck?

A feeding problem or a hidden scrap can trigger a jam message, but the cause depends on the model. Follow its jam-clearing procedure, check the supported media and try plain paper. Contact the manufacturer if the error continues.

Can a normal home printer print on 300gsm card?

Some models support particular 300gsm media, but others do not. Check the exact model’s tray-specific weight, thickness and media restrictions. A rear feed does not by itself guarantee compatibility.

Why does thick card come out crooked?

The sheet may be misaligned, curled or feeding unevenly. Check the loading position and guides, use flat supported stock and follow any recommended maintenance steps.

What printer setting should I use for card?

Use the media setting recommended by your printer manufacturer for that stock, and select the correct tray and paper size. Do not assume the heaviest available setting is always the right one.
