device for digitizing documents
A machine that you use to make a digital copy of a paper document or photo on a computer.
Модел на употреба:
use a scanner to copy [document]
Честа грешка:
Learners sometimes confuse 'scanner' with 'printer'. A scanner sends a paper image into the computer, while a printer sends an image or text from the computer onto paper. Another mistake is calling a scanner a 'scan machine'; in natural English, people just say 'scanner'.
Синоними
digitizer (More technical; often refers to any device that converts physical information into digital form, not just documents.)
|
copier (Usually means a machine that both scans and prints; focuses on making paper copies rather than digital images only.)
Антоними
printer (Performs the opposite direction of conversion, turning digital files into physical pages instead of pages into digital files.)

device for reading barcodes
A machine in a store or other place that reads the black and white lines or square codes on things to get the price or other information.
Модел на употреба:
pass [item] over the scanner
Честа грешка:
Learners may think this is the same as a document scanner, but a barcode scanner usually reads lines or patterns to get data like price or product ID, not a full picture of a page.
Синоними
barcode reader (More technical but very close in meaning; emphasizes the function of reading the code rather than the physical device.)

medical machine for body imaging
A big machine in a hospital that takes detailed pictures of the inside of your body, for example a CT scanner or an MRI scanner.
Модел на употреба:
go into the scanner for [test]
Честа грешка:
Learners may confuse this with a simple X-ray machine. A 'scanner' in a hospital usually means more complex imaging, like CT or MRI, that creates many detailed slices or 3D pictures.
Синоними
imaging machine (More general term; can refer to several types of medical devices that create images, not only scanners.)

security device for checking items
A machine at places like airports that looks inside bags or at your body to find dangerous things.
Модел на употреба:
pass [person/object] through the scanner
Честа грешка:
Learners sometimes call this machine a 'metal detector' even when it uses other technology, like X‑rays or full‑body scanning. 'Scanner' is a broader word for these security machines.
Синоними
security screener (Can refer to a person or a machine; focuses on the security role rather than the technology.)

radio device scanning frequencies
A special radio that quickly moves through many channels and stops when it finds someone talking, for example police or emergency workers.
Модел на употреба:
listen to [service] on the scanner
Честа грешка:
Learners may think this is the same as a normal radio. A scanner does not stay on one station; it moves quickly through many frequencies and stops only when there is a signal.
Синоними
radio scanner (More specific term that makes clear the device works with radio signals.)
Антоними
radio jammer (Instead of receiving and playing signals, a jammer blocks or interferes with them, which is functionally opposite.)

software that scans for issues
A computer program that checks files or a system to find problems like viruses or security risks.
Модел на употреба:
run a scanner on [system/files]
Честа грешка:
Learners sometimes think a 'virus scanner' is only hardware. In computing, a scanner can be a pure software program with no separate physical device.
Синоними
scanner tool (Makes it clear that this is software; still somewhat technical jargon.)
|
checker (More informal and general; can refer to any program that checks for problems, not only security issues.)

person who reads quickly for details
A person who reads something quickly to find certain words, numbers, or facts.
Модел на употреба:
be a fast scanner of [type of text]
Честа грешка:
Learners may assume 'scanner' always means a machine. In study skills and reading contexts, 'scanner' can refer to a person, though this use is less common and often appears in more academic or descriptive language.
Синоними
skimmer (Suggests reading lightly over the surface; often with a slight negative sense of not reading carefully.)
Антоними
close reader (Emphasizes slow, detailed reading of every part of the text, opposite to scanning for specific details.)
