A photocopy is a physical duplicate of a document made by a machine that scans the original and prints an identical copy onto paper

When you place a document on a photocopier, the machine uses light and heat to transfer an image of that document onto a blank sheet of paper. The result looks like the original — same text, same images, same layout — but it is a separate physical piece of paper. Photocopiers are found in offices, libraries, schools, and print shops. You can make one copy or hundreds of copies in minutes.

The word "photocopy" comes from the process itself: "photo" means light, and "copy" means duplicate. The machine photographs the document electronically and then copies that image onto paper. This is different from scanning, which creates a digital file on a computer, or printing, which produces copies from a digital file you already have on screen.

Key Takeaways

  • A photocopy is a paper duplicate made by a machine that scans and prints an image of the original document in one step.
  • Photocopiers work by using light to read the document, then using heat and toner (a fine powder) to transfer that image onto blank paper.
  • You can photocopy documents in color or black-and-white, and most machines let you enlarge or reduce the size of the copy.
  • Photocopies are useful for sharing documents, creating backups, or making multiple versions without needing a printer and computer.

How a photocopier actually works

Inside a photocopier is a drum — a cylinder coated with a material that holds an electrical charge. When you place your document in the machine and press the copy button, a bright light scans across the document. The light reflects off the paper and is focused onto that charged drum. Dark areas of your document (like text or images) reflect less light, so those spots on the drum lose their charge. Light areas (like blank paper) reflect more light, so those spots keep their charge.

Next, the machine applies toner — a fine black or colored powder — to the drum. The toner sticks only to the areas that still have a charge, creating a mirror image of your document. A blank sheet of paper is rolled against the drum, and the toner transfers onto it. Finally, heat rollers fuse the toner to the paper permanently, and your copy comes out the other side.

This entire process happens in seconds. Modern photocopiers can produce 20 to 100 copies per minute, depending on the machine's speed and whether you are copying in color or black-and-white.

Photocopies versus scanning and printing

A photocopy is a one-step process: document in, copy out. A scan-and-print workflow is two steps: first you scan the document into a computer as a digital file, then you print that file. Photocopying is faster if you just need paper copies right now. Scanning is better if you want to store the document on your computer, email it, or edit it later.

Photocopiers also do not require a computer. You can walk up to a machine in a library or office, place your document on the glass, press a button, and walk away with copies. With scanning and printing, you need access to both a scanner and a printer, plus a computer to manage the file in between.

When you would use a photocopy

You photocopy documents when you need multiple paper versions quickly and do not need a digital file. Common reasons include making copies of a receipt or bill to keep for your records, duplicating a contract so each party has a signed copy, or creating handouts for a meeting or class. Landlords often ask tenants to photocopy their lease so both sides have a copy to keep.

Photocopies are also useful when you need to send a document by mail but want to keep the original. Instead of mailing your only copy, you photocopy it and mail the copy, keeping the original safe at home. Some organizations require photocopies of documents like driver's licenses or utility bills as proof of identity or address — they want a paper copy, not a digital scan.

Cost and where to find a photocopier

The cost of a photocopy varies by location. Most public libraries offer photocopying for 5 to 25 cents per page in black-and-white, with color copies costing more. Office supply stores like Staples or FedEx Office charge similar rates and may offer discounts if you copy many pages at once. Some workplaces and schools let employees or students use photocopiers for free.

If you photocopy regularly, you might consider buying a home photocopier, though they are expensive and take up space. Most people find it cheaper and more practical to use a library or print shop when they need copies occasionally.

Quality and limitations of photocopies

A photocopy is usually very close to the original, but not perfect. If the original document has faint text or poor image quality, the copy may be even fainter. Photocopies of photocopies get progressively worse — each generation loses detail. If you need a high-quality copy of an important document, scanning it and printing from the digital file often produces a better result.

Photocopiers also cannot copy three-dimensional objects or very thick books. They work best with flat, single-sheet documents. Some machines struggle with colored paper or very small text. If you are copying something unusual, it is worth testing on one copy first before making a large batch.

Photocopies and legal documents

Many organizations accept photocopies of documents like driver's licenses, utility bills, or lease agreements. However, some situations require certified copies — official duplicates made by a government office or notary public. A regular photocopy from a library machine is not a certified copy and will not work for legal purposes like opening a bank account or explore for a passport.

If you are unsure whether a photocopy is acceptable, ask the organization that requested the document. They can tell you whether a regular photocopy is fine or whether you need a certified copy from a government office.

Frequently Asked Questions

Can I photocopy money or important government documents?

No. It is illegal to photocopy currency in most countries. Photocopying government documents like passports or Social Security cards is also illegal unless you have permission from the government agency. Some documents, like driver's licenses, can be photocopied for personal records but not for fraud or identity theft.

What is the difference between a photocopy and a printout?

A photocopy comes directly from a physical document using a photocopier machine. A printout comes from a digital file on a computer sent to a printer. Photocopies are faster if you already have the paper document. Printouts are better if you have the document on your computer and want to make changes before printing.

Why do photocopies sometimes look blurry or faded?

If the original document is faded or has light text, the photocopy will be even fainter because the machine copies what it sees. Dirty glass on the photocopier or low toner levels can also cause blurry copies. Cleaning the glass or replacing the toner usually fixes the problem.

Can I enlarge or reduce a document when I photocopy it?

Yes. Most photocopiers have buttons to enlarge (make bigger) or reduce (make smaller) the copy. You can usually adjust the size from 50 percent to 200 percent of the original. This is useful if you want to make text larger for easier reading or shrink a large document to fit on fewer pages.
